OLD DOMINION SPEEDWAY
2008 RULES AND REGULATIONS
Version LMSC2008.A Effective 2/2/08 PRINTABLE VERSION – LMSC RULES
The LMSC division is Old Dominion Speedway’s premier division. The cars are to be prepared in accordance with the 2008 NASCAR Rule Book, section 20F, and any NASCAR Technical Bulletins released which effect the LMSC division. These rules are subject to amendment at any time when notice has been given. Notice shall be deemed effective within two (2) weeks of the rule amendment and posting of the rule change by Old Dominion Speedway (ODS).
NOTE: In an effort to reduce costs and improve competition for the 2008 season, ODS will run cars meeting the 2008 LMSC or 2008 Grand Stock Rules and Regulations together in a track division to be known as “ODS Late Model.” Performance will be monitored closely and adjustments made as necessary to maintain parity. Engines will be subject to tear-down for tech inspection. 2008 LMSC and 2008 Grand Stock division cars will be permitted to meet the shock absorber requirements set forth in either the 2007 or 2008 NASCAR Whelen All-American Series rulebook.
In 2008, starting inversions for the ODS Late Model division will be based on the average number of points earned by qualified entries over the previous three (3) races. The winner of the last race will start in sixth position. The top qualifiers will then be inverted for the remaining positions with the entry with the highest average in fifth position, the next highest in fourth, and so on. If a qualifier missed one of the three previous events, the inversion calculation will assume win points for that event.

5.4 CRATE ENGINE RULES AND PENALTIES
A. If the engine/seal numbers/etc. are not in the main database, that competitor will not run. If it is not sealed or not sealed with the agreed upon seal of the southeast speedways, they will not run. A competitor without the southeast speedways’ sealed crate engine will have the option to rent, borrow, or buy (depending on the speedway the competitor is attempting to race at) a sealed crate engine from that speedway.
B. All crate engines must run an H.E.I. type electronic ignition with an internal built-in rev limiter (maximum allowed is 6500 RPM) or a dual-point ignition. The coil must be mounted on the engine side of firewall as close as possible. No amplifier boxes; no MSD boxes; no magnetos. (Mel’s Ignition is recommended.)
C. Balancers must be original. They cannot be changed. Timing covers MAY NOT be changed. Everything must be the original. NO EXCEPTIONS.
D. If during technical inspection, at any time, a racer’s crate engine is found to have been altered, tampered with, opened, resealed, or wrong for any reason what so ever (and there is no explanation of it in the master database), the engine is illegal. The penalty for this is as follows:
Disqualification of that race – 0 points, $0.00 in prize money won during the race, including, but not limited to Pole Award; NASCAR suspension of the next (2) race weekends at that participants home track (for example – if Tom Smith is suspended for 2 races and the next 2 races are rained out, Tom Smith will remain suspended until 2 points events have passed where racing has occurred at that speedway. This allows for the possibility of Tom Smith missing 4 races.); probation for the remainder of the current season; and a NASCAR Fine of $1,000.00. The racer will not be allowed to race at any NASCAR track until the fine has been paid.
Disqualification of that race – 0 points, $0.00 in prize money won during the race, including, but no limited to Pole Award; NASCAR suspension of the next (4) points events at that participants home track (see above example of Tom Smith; he may now miss 8 races); probation for the remainder of the current season; and a NASCAR Fine of $2,000.00. The racer will not be allowed to race at any NASCAR track until the fine has been paid.
Disqualification of that race – 0 points, $0.00 in prize money won during the race, including, but no limited to Pole Award; NASCAR suspension for AT LEAST the remainder of the current season; and a NASCAR Fine of $5,000.00. The racer will not be allowed to race at any NASCAR track until the fine has been paid and a sufficient amount of time served for suspension has passed. Once that racer returns, he/she will be on probation (length to be determined).
ADDITIONALLY, each time a crate engine has been found illegal, that track will confiscate the engine. The engine will be unbolted at the bell housing and removed. Everything, including, but no limited to, the carburetor, engine mounts, clutch, belts, air cleaner/filter, and the oil pan will be removed from the racecar and confiscated by the track. IT WILL NOT BE RETURNED UNDER ANY CIRCUMSTANCES.
E. If a carburetor does not pass technical inspection after the race, the racer will be disqualified for that night and forfeit all points and prize money. The racer will receive 0 points and $0.00 in prize money. The carburetor will be confiscated by the track and will not be returned. A $500.00 NASCAR fine will be levied. The racer will not be allowed to race at any NASCAR track until the fine has been paid. If a carburetor does not pass technical inspection after Qualifying, but BEFORE the Green Flag, the carburetor will be confiscated, a $500.00 Track fine will be levied, all winnings up to that point will be forfeited, and the racer will start at the rear of the field. The racer will not be allowed to start the race that night or any other races at a NASCAR track until the $500.00 fine has been paid. (The only things that can be changed on the carburetors are the power valves and jets. If anything else is different, then the carburetor is illegal.)
F. Carburetor Claim/Exchange. Any racer that finishes in the Top 5 will have the option to claim another competitor’s carburetor that finished in the Top 5 that same race. The claim fee is $200.00. Both carburetors must pass technical inspection before exchanging. If a claim exchange is approved, both carburetors must be left at the track and at the next race, the Track Officials will ensure that the carburetor are put on and run. The Track reserves the right to deny any request for a Claim/Exchange.
Additionally, the owner of the claimed carburetor may opt to have the claimer buy his carburetor for a fee of $700.00. (This forfeits the $200.00 Claim Fee & the driver of the claimed carburetor will not receive the other’s carburetor.) The Track reserves the right to deny any request for a Claim.
Speedwayreserves the right to an exchange at any time during the night with any competitor. This will be a straight exchange with no money switching hands.
G. There will be no claim or claim/exchange on the crate engines by competitors. The track has the right to pull an engine and check it at any time. If it is wrong, the above penalties will apply. If it is right, the Track will return the engine in a timely manner. The track reserves the right to impound anyone’s car or any part of anyone’s car for the purpose of technical inspection. If a racer refuses to allow his car to go through technical inspection, then the track will impound the car until the racer agrees to allow his car to be teched.
5.5 Crate engines may be freshened through the racetrack. The engine will be worked on by the track’s designated engine builder and resealed by the track before being returned to the competitor. The track reserves the right to refuse a request for a refresh. Engines that have obvious problems, oil pressure, valve train, etc. can be fixed within this refresh rule. Under NO circumstances will the engine be re-bored. A typical refresh will involve replacement of the following parts: bearings, rings, gaskets and valve springs and a GM factory finish applied to the valves / valve seats. Additional parts may be replaced if wear is noted. The engine will be resealed by the track and dyno tested before it is returned to the competitor.
6. Car Weight After Competition
Cars must weigh a minimum of 3100 pounds with a minimum right side weight of 1400 pounds with the following after race weight allowance for fuel and fluids consumed. The weight allowance will be seven tenths (.70) pound per race lap with no tolerance. Half of this allowance will be for the right side weight requirement. In the event of twin races, the weight allowance requirements will apply to each race on an individual basis. Example: Twin 100 lap races. After the first 100 lap race, the car’s minimum allowed weight is 3030. After the second 100 lap race, the car’s minimum allowed weight is still 3030 pounds.
7. MIRRORS 7.1 A side-mounted rear view mirror may be installed.
8.1 All competitors should read/review sections 1 thru 17 of the NASCAR 2008 Rule Book.
8.2 All competitors should read/review ODS General Rules and ODS All Division Rules. Any questions concerning these rules should be directed to a member of the ODS technical crew.
