<p><b>Modified stock car racing</b>, also known as <b>modified racing</b> and <b>modified</b>, is a type of <a href="Auto_racing" title="Auto racing">auto racing</a> that involves purpose-built cars simultaneously racing against each other on <a href="Oval_track_racing" title="Oval track racing">oval tracks</a>. First established in the United States after <a href="World_War_II" title="World War II">World War II</a>, this type of racing was early-on characterized by its participants' modification of passenger cars in pursuit of higher speeds, hence the name.

</p><p>There are many sanctioning bodies for modifieds, each specifying different body styles and engine sizes.

</p>

<div class="mw-heading mw-heading2"><h2 id="History">History</h2></div>

<p>A typical early "modified stock car" was, as its name implies, generally a stock automobile, with the glass removed, a roll cage installed, and a souped-up motor. <a href="NASCAR" title="NASCAR">NASCAR</a> began by organizing the modifieds, and ran its first race in Daytona Beach in February 1948 at the beach road course.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> (In June 1949, NASCAR organized its first "<a href="NASCAR_Cup_Series#Strictly_Stock_and_Grand_National" title="NASCAR Cup Series">strictly stock</a>" later model car race at Charlotte, North Carolina, which evolved into its well known premiere division.)

</p><p>What started out as minor modifications to the cars became visibly apparent as the bodies were channeled and lowered. The car builders started mixing and matching components from different car makers. Some modified classes are no longer based on any current production vehicles. Modified racing remained popular, particularly on the east coast, and grew away from "<a href="Strictly_Stock" class="mw-redirect" title="Strictly Stock">strictly stock</a>" or "<a href="Late_Model" class="mw-redirect" title="Late Model">Late Models</a>" and became akin to both stock cars and open-wheel cars. Until the early 1970s, drivers typically competed on both dirt and asphalt surfaces with the same car.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup>

</p><p>Modified cars resemble a hybrid of open wheel cars and stock cars. The rear wheels are covered by fenders but the front wheels and engine are left exposed. There are sanctioning bodies that control the rules for this class at most tracks. Each sanctioning body has their own set of guidelines provided in an annual rule book and their own registration fees.

</p>

<div class="mw-heading mw-heading2"><h2 id="Asphalt_modified">Asphalt modified</h2></div>

<p>Modifieds designed solely for asphalt surfaces began appearing in the early 1970s. These modifieds sit on large slick tires that are exposed on all four corners of the car. The roofs of these cars are more rounded than the other types of modifieds, their bodies look somewhat squashed and have large spoilers on the rear of the cars. Drivers sit on the left side of the car, and most of the time will have some type of small plastic windshield in front of them. Asphalt Modifieds are most popular in the Northeast but can be found from Florida to Texas to Michigan under different sanctioning bodies, as well as unsanctioned local classes. The rules packages may vary greatly.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup>

<p>The Midwest Modifieds Tour started in 1989 as the E-Mod Series at Mount Lawn Speedway near Indianapolis IN. It has undergone several name changes including ICAR, NSTA Top Speed Modified Tour, and the USA Modified Series. This travelling series races at local short tracks in Indiana, Michigan, and Ohio. In 2013 they raced for the first time on a road course, near South Haven, Michigan, at Gingerman Raceway. The series changed hands for 2017, from ICAR to NSTA, after being purchased by John Robbins (nephew of the former ASA pioneers) from Dave Muzillo.<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup>

The series originally started on dirt, and as more and more asphalt tracks opened, the series migrated to racing on the newer tracks. The series also had previously made forays into road racing with stops at <a href="Watkins_Glen_International" title="Watkins Glen International">Watkins Glen International</a> in <a href="New_York_(state)" title="New York (state)">New York</a>.<sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup> Drivers like <a href="Bobby_Allison" title="Bobby Allison">Bobby Allison</a> and <a href="Red_Farmer" title="Red Farmer">Red Farmer</a> started in the NASCAR Modified series, which was popular both in the south and the Northeast.

<div role="note" class="hatnote navigation-not-searchable">Main article: <a href="Race_of_Champions_(modified_racing)" title="Race of Champions (modified racing)">Race of Champions</a></div>

<p>The Race of Champions Asphalt Modified Series was first developed by Andrew Harpell in 1994 as the <i>New York Modified Series.</i><sup id="cite_ref-9" class="reference"><a href="#cite_note-9"><span class="cite-bracket">[</span>9<span class="cite-bracket">]</span></a></sup> Harpell subsequently purchased the historic Race of Champions, and rebranded the series upon creation of a separate Dirt Modified Tour in 2005.<sup id="cite_ref-10" class="reference"><a href="#cite_note-10"><span class="cite-bracket">[</span>10<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-11" class="reference"><a href="#cite_note-11"><span class="cite-bracket">[</span>11<span class="cite-bracket">]</span></a></sup>

<p>In late 2004, NASCAR bought out the Southern Modified Auto Racing Teams (SMART), and promptly renamed it the NASCAR Whelen Southern Modified Tour.<sup id="cite_ref-CircleTrackNovember2007_12-0" class="reference"><a href="#cite_note-CircleTrackNovember2007-12"><span class="cite-bracket">[</span>12<span class="cite-bracket">]</span></a></sup> The southern tour uses exactly the same set of rules as the northern tour, but races primarily in the southeastern section of the US.

<div class="mw-heading mw-heading3"><h3 id="Northeast_dirt_modified">Northeast dirt modified</h3></div>

<p>The late <a href="Toby_Tobias" title="Toby Tobias">Dick Tobias</a> from Pennsylvania revolutionized the chassis of the dirt track modified stock car class in the early 1970s by producing an entirely homemade chassis constructed of tubular steel.<sup id="cite_ref-14" class="reference"><a href="#cite_note-14"><span class="cite-bracket">[</span>14<span class="cite-bracket">]</span></a></sup>

Race promotors, drivers and car builders who focused on the dirt tracks in northeastern U.S. and southeastern Canada, became eager for standardized rules. In 1976, the Driver's Independent Race Tracks (DIRT) was organized, and rules were implemented where the driver sits in the middle of the car, with high-downforce, wind-channeling tunnels on either side of him. Other promoters and sanctioning bodies in the region adopted similar rules shortly thereafter. The roofs are very flat, and tilted to catch additional air. The front suspension is usually a coil-over setup, with a torsion-bar set-up for the rear suspension. They utilize full tube chassis, which to the untrained eye, looks like a sprint car chassis, but is much different in reality.

</p>

<div class="mw-heading mw-heading4"><h4 id="Small_block_modifieds"><i>Small block modifieds</i></h4></div>

<p>The small block or "358 modifieds" emerged from <a href="NASCAR_Sportsman_Division" title="NASCAR Sportsman Division">NASCAR's Sportsman division</a>, which had been formed in 1950 as NASCAR's <a href="Short_track_motor_racing" class="mw-redirect" title="Short track motor racing">short track race</a> division. The sportsman cars were older model cars and could be modified, but not as much as the <a href="Whelen_Modified_Tour" class="mw-redirect" title="Whelen Modified Tour">Modified series cars</a>. By 1967 the limitations had evolved to include small block engines, a single carburetor and pump gasoline. The norm for many NASCAR-sanctioned tracks was that Modifieds and Sportsmen raced side by side, but top-finishing Sportsmen received bonus money, and separate points were tallied for both divisions.<sup id="cite_ref-15" class="reference"><a href="#cite_note-15"><span class="cite-bracket">[</span>15<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-ARRA1_16-0" class="reference"><a href="#cite_note-ARRA1-16"><span class="cite-bracket">[</span>16<span class="cite-bracket">]</span></a></sup>

</p><p>Looking to differentiate the Sportsman as a truly separate class and expecting spectators to relate better to newer model cars, NASCAR dropped the pre-war coupes and sedans for the 1968 season, substituting the <b>Late Model Sportsman Series</b> (later to become the <a href="NASCAR_Xfinity_Series" title="NASCAR Xfinity Series">Xfinity Series</a>) with 1955 and newer bodies.<sup id="cite_ref-ARRA1_16-1" class="reference"><a href="#cite_note-ARRA1-16"><span class="cite-bracket">[</span>16<span class="cite-bracket">]</span></a></sup>

</p><p>Several non-sanctioned venues in the Northeast continued to run a combined support class with old and new bodied sportsman. Notably the <a href="Watertown_Speedway" title="Watertown Speedway">Watertown Speedway</a> in Northern New York had a shared rule book with the <a href="Kingston_Speedway" title="Kingston Speedway">Kingston Speedway</a> in Ontario, Canada limiting engines for their primary class to the old <a href="Ford_flathead_V8_engine" title="Ford flathead V8 engine">Ford flathead V8</a> and <a href="Chevrolet_Stovebolt_engine" title="Chevrolet Stovebolt engine">Chevrolet inline 6 cylinders</a>. In 1968, they updated their rules to allow the newer small block engines, attracting the pre-war coupes from <a href="Saranac_Lake_Speedway" title="Saranac Lake Speedway">Saranac Lake</a> and <a href="Fort_Covington_International_Speedway" title="Fort Covington International Speedway">Fort Covington International Speedways</a>, and the neighboring <a href="Evans_Mills_Raceway_Park" title="Evans Mills Raceway Park">Evans Mills Speedway</a> opened with similar rules.<sup id="cite_ref-17" class="reference"><a href="#cite_note-17"><span class="cite-bracket">[</span>17<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-18" class="reference"><a href="#cite_note-18"><span class="cite-bracket">[</span>18<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-:0_19-0" class="reference"><a href="#cite_note-:0-19"><span class="cite-bracket">[</span>19<span class="cite-bracket">]</span></a></sup> Propelled by the strong economics of southeastern Canada's metropolitan areas, the nearby <a href="Brockville_Ontario_Speedway" title="Brockville Ontario Speedway">Brockville Ontario</a> and <a href="Cornwall_Motor_Speedway" title="Cornwall Motor Speedway">Cornwall Motor Speedways</a> soon opened, and the "small blocks" became the premiere class in the <a href="St._Lawrence_River" title="St. Lawrence River">St. Lawrence River</a> Valley.<sup id="cite_ref-:0_19-1" class="reference"><a href="#cite_note-:0-19"><span class="cite-bracket">[</span>19<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-20" class="reference"><a href="#cite_note-20"><span class="cite-bracket">[</span>20<span class="cite-bracket">]</span></a></sup>

</p><p>The DIRT organization eventually standardized the engine sizes across its member tracks to 320 cubic inches, and later to 358 cubic inches.<sup id="cite_ref-OCFS1_21-0" class="reference"><a href="#cite_note-OCFS1-21"><span class="cite-bracket">[</span>21<span class="cite-bracket">]</span></a></sup> In 1983, the <a href="Super_DIRTcar_Series#Mr._DIRTcar" title="Super DIRTcar Series">Mr. Dirt 320 Modified Championship</a> trail was created, pitting the "St. Lawrence Valley small blocks" against their counterparts in the <a href="Hudson_Valley" title="Hudson Valley">Hudson Valley</a> and the <a href="Twin_Tiers" title="Twin Tiers">Twin Tiers</a> regions of Pennsylvania and New York, thus restoring the status of the class throughout the Northeast.<sup id="cite_ref-BS12_22-0" class="reference"><a href="#cite_note-BS12-22"><span class="cite-bracket">[</span>22<span class="cite-bracket">]</span></a></sup>

</p>

<div class="mw-heading mw-heading4"><h4 id="Sportsman_modifieds"><i>Sportsman modifieds</i></h4></div>

<p>Not to be confused with the former NASCAR Sportsman class, in 1987 a new Sportsman Division was created by the DIRT organization to help new and underfunded drivers learn how to work with and drive the same chassis as a modified. Although cars are identical to the naked eye, the sportsman engines are about 500 horsepower compared to the 750-800 horsepower, 467-cubic inch big blocks in the modifieds. The new division increased the gate revenues at the pit window, and created new customers for modified teams to sell their used cars to. It also put more cars on the market in the offseason, lowering prices and allowing both divisions to grow.<sup id="cite_ref-OCFS1_21-1" class="reference"><a href="#cite_note-OCFS1-21"><span class="cite-bracket">[</span>21<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-23" class="reference"><a href="#cite_note-23"><span class="cite-bracket">[</span>23<span class="cite-bracket">]</span></a></sup>

</p><p>Promotors in the northeast have also introduced a <b>Limited Sportsman</b> class. Although there may be some cost saving restrictions on the cars, the primary limitation rests with the experience level of the drivers.<sup id="cite_ref-24" class="reference"><a href="#cite_note-24"><span class="cite-bracket">[</span>24<span class="cite-bracket">]</span></a></sup>

<p>Sanctioning bodies WISSOTA Promoters' Association and <a href="United_Midwestern_Promoters" class="mw-redirect" title="United Midwestern Promoters">United Midwestern Promoters</a> (UMP) also have classes that are almost identical to IMCA's modifieds, with a few small exceptions. The AMRA, or American Motor Racing Association also follows this popular formula for modifieds.<sup id="cite_ref-30" class="reference"><a href="#cite_note-30"><span class="cite-bracket">[</span>30<span class="cite-bracket">]</span></a></sup> NASCAR drivers <a href="Ken_Schrader" title="Ken Schrader">Ken Schrader</a> and <a href="Kenny_Wallace" title="Kenny Wallace">Kenny Wallace</a> own and race UMP Modifieds on off weekends from NASCAR.

</p>

<div class="mw-heading mw-heading4"><h4 id="IMCA_SportMods"><i>IMCA SportMods</i></h4></div>

<p>IMCA designed a new lower-cost class of SportMod cars in 2004 to complement its Modified division. The division is divided into Northern SportMods and Southern SportMods divisions. The Northern SportMods have a few small differences from the Southern SportMods in the body of the car. These cars are somewhat smaller and have less powerful engines.<sup id="cite_ref-31" class="reference"><a href="#cite_note-31"><span class="cite-bracket">[</span>31<span class="cite-bracket">]</span></a></sup> They can be differentiated from IMCA Modifieds because the car has a break in the body that extends from the rear roof to the spoiler at the rear.

</p>

<div class="mw-heading mw-heading4"><h4 id="Afco_KidModz"><i>Afco KidModz</i></h4></div>

<p>This relatively inexpensive (when compared to their "adult" counterparts) racing series is aimed at attracting younger drivers as an entry-level class. It closely follows UMP's Modified rules, with a few exceptions. The engine must be a <a href="Ford_Pinto_engine" title="Ford Pinto engine">2300cc Ford Pinto</a> (also known as a Lima) inline 4-cylinder, and the drivers can be no younger than 12, nor older than 18. Some tracks will allow children aged 10 or 11 to race if the track's insurance will allow. The KidModz are also allowed to run tubular chassis, whereas the IMCA/WISSOTA/UMP Modifieds have to have sections of frames from stock production automobiles, with other sections being steel tubing. These cars are offered for sale completely assembled and ready-to-race for under $20,000. The unassembled price is lower.<sup id="cite_ref-32" class="reference"><a href="#cite_note-32"><span class="cite-bracket">[</span>32<span class="cite-bracket">]</span></a></sup>

They also are allowed to utilize quick-change rear ends and aluminum wheels, whereas the IMCA modifieds are forced to race with heavier cast-iron engines, partial stock frames, steel wheels and Ford 9-inch (230 mm) rear ends.<sup id="cite_ref-34" class="reference"><a href="#cite_note-34"><span class="cite-bracket">[</span>34<span class="cite-bracket">]</span></a></sup>

<p>One type of Outlaw Modified can be found in the <a href="Arkansas" title="Arkansas">Arkansas</a>, <a href="Louisiana" title="Louisiana">Louisiana</a>, and <a href="Texas" title="Texas">Texas</a> area. They are called Ark-La-Tex Winged Modifieds. These outlaw modifieds sport full tube chassis, and bodies that look like the Advanced Auto Parts Super DIRTcar racers, with the exception of the <a href="Sprint_car" class="mw-redirect" title="Sprint car">sprint car</a>-like wing affixed to the roofs of the cars. These cars can also be found deeper into Texas such as Dallas and Waco. They are not always bodies that look like the Advance Auto Parts Super DIRTcar racer with a wing, some of the Winged Modifieds use bodies called skinny bodies that are not currently being made, but some drivers still have these. Winged Modified racing began at Boothill Speedway in Greenwood, LA and spread throughout the area, soon Heart O' Texas Speedway in Waco was running them, so on Friday nights anybody from the <a href="Ark-La-Tex" title="Ark-La-Tex">Ark-La-Tex</a> went to Waco and drove Winged Modifieds there, and on Saturday nights they were at Boothill Speedway. Some of the US' biggest legends started racing winged modifieds such as Sprint Car Veteran Gary Wright of Hooks, Texas, National Dirt Late Model Hall of Famer and Boothill Speedway Hall of Fame Inductee Doug Ingalls of Longview, Texas, Boothill Speedway Hall of Fame inductee "Papa" Ray Ingalls of Longview, Texas, Late Model Veteran and Boothill Speedway Hall of Fame inductee Ronny Adams of Greenwood, Louisiana, Heart O' Texas Speedway Wall of Fame inductee Eldon Dotson of Allen, Texas, Heart O' Texas Speedway Wall of Fame inductee Joe Sturdivant of Elgin, Texas, and 2010 Ark-La-Tex Wing Modified Champion, 2011 SMP Series Longhorn Champion and 38th Annual Louisiana State Dirt Track Championships winner at Boothill Speedway 19-year-old Tyler Townsend from Longview, Texas.<sup id="cite_ref-35" class="reference"><a href="#cite_note-35"><span class="cite-bracket">[</span>35<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-36" class="reference"><a href="#cite_note-36"><span class="cite-bracket">[</span>36<span class="cite-bracket">]</span></a></sup>

<p>One type of outlaw modified in <a href="Alberta" title="Alberta">Alberta</a>, <a href="Canada" title="Canada">Canada</a>, races on both dirt and asphalt, with the same cars.

</p>

<div class="mw-heading mw-heading3"><h3 id="Outlaw_Modified_Racing_Series">Outlaw Modified Racing Series</h3></div>

<p>Organized in Florida in the 1970s, these Outlaw Modifieds are fairly unusual. They are built on tube chassis with coil over shocks. 10-inch-wide (250 mm) tires and a 76-inch (1,900 mm) track make these cars are fast and nimble. 2300 cc, four-cylinder power plants from Fords, <a href="Toyotas" class="mw-redirect" title="Toyotas">Toyotas</a> and even an odd <a href="Nissan" title="Nissan">Nissan</a> are common, but the <a href="Ford_Pinto_engine" title="Ford Pinto engine">Ford Pinto Lima</a> is the favored motor. Motor rules have stayed very stable over the last ten years with the only rule change coming in 2008 which allowed the Esslinger aluminum d-port head, due to the declining availability of the cast-iron cylinder heads. These cars are set apart from most modified racing series in that they do not utilize roofs on the cars.<sup id="cite_ref-38" class="reference"><a href="#cite_note-38"><span class="cite-bracket">[</span>38<span class="cite-bracket">]</span></a></sup>

<p>US Legend Cars International of <a href="Charlotte%2C_North_Carolina" title="Charlotte, North Carolina">Charlotte, North Carolina</a>, created the <a href="Legends_car_racing" title="Legends car racing">Legends</a> series (while they were named 600 Motorsports) as a way of attracting more and younger people into racing with affordable cars. The cars were designed to be 5/8-scale 1930s and 1940s coupes and sedans cars raced in the past in the <a href="NASCAR" title="NASCAR">NASCAR</a> <a href="Whelen_Modified_Tour" class="mw-redirect" title="Whelen Modified Tour">Modified Tour</a>. They all have a tube chassis and spec 1250 cc Yamaha Motorcycle engines.

</p>

<div class="mw-heading mw-heading3"><h3 id="Dwarf_cars">Dwarf cars</h3></div>

<p>Dwarf cars are similar to the Legends cars, in that they are scale replicas of vintage race cars. The similarity ends there, as Dwarf cars are true open "modified-style" cars without fenders, and have a 1,250 cc (76 cu in) limitation on the engine size. The Western States Dwarf Car Association, begun in 1993, has become one of the most successful racing organizations, boasting an average of 80–100 Dwarf Cars at 4 National, and several regional, events a year.<sup id="cite_ref-39" class="reference"><a href="#cite_note-39"><span class="cite-bracket">[</span>39<span class="cite-bracket">]</span></a></sup>

</p><p>There is also a class of Dwarf Cars that race on dirt called the Vintage Lite Series. They race a mixed field of cars, some resembling the vintage cars and some scaled-down versions of the current modified dirt cars (these cars are often referred to as the MiniMods).

</p>

<p>The Mod Lite is a 5/8th scale race car that resembles the northeast dirt modifieds, but is powered by a 190-200hp 1,000cc stock 16-valve motorcycle engine. Most racers use the Suzuki GSXR 1000 or Kawasaki ZX 10.<sup id="cite_ref-40" class="reference"><a href="#cite_note-40"><span class="cite-bracket">[</span>40<span class="cite-bracket">]</span></a></sup>
