The intention of these rules is to provide an easy-to-understand guide to the F.A.S.T. style of drag racing. Which is to look stock, sound stock and run fast, the way muscle cars should, while having fun and building camaraderie among fellow muscle car enthusiasts, and following the intent or spirit of the F.A.S.T. rules. However, there may come a time when a participant misinterprets the F.A.S.T. intent. In all instances, the F.A.S.T. Board will make the final interpretation on the rules. If you believe that you have a valid reason why your car could not follow the letter of the following rules, contact the F.A.S.T. Board for a decision.

F.A.S.T. racing is for 1955 to 1974 muscle cars built in United States and Canadian assembly plants. Factory lightweight cars built for sanctioned drag racing and dealership built/modified cars are not eligible to participate. Cars must have been originally equipped with a minimum of four-barrel carburetion, dual exhaust, and other factory installed equipment that promotes a high performance image.

NOTE: Throughout this rules document, all references to “correct*” acknowledge that it is “proper for the year, make, model and horsepower claimed, for both the car and engine claimed. The car year, make, model, body style and engine combination must all have been produced and available to the general public in the year claimed, in an actual car.”

Most parts of the car will fall into one of four categories:

1) Correct* OEM parts. These parts must be proper for the year, make, model, and horsepower claimed, and they must be Original Equipment Manufactured (OEM) parts. Examples: Intake manifold and cylinder heads.

2) Correct* parts. These parts are the same as Correct* OEM parts, except they do not need to be OEM manufactured. Reproduction parts, that duplicate the Correct* Original parts in appearance, form, function and material and are primarily designed as “restoration” parts are allowed, as long as they comply with all other applicable rules. Examples: wheels, upholstery, emblems, replacement sheet metal, etc.

3) Spec parts. Parts that meet a specification defined in the rules, but are not necessarily Correct* or stock appearing. Examples: tires, exhaust system. Note: Every effort should be made to achieve a stock “look” with these parts. For example; your car did not come from the factory with a 2-1/2” mandrel bent exhaust system. But it is specified in the rules that you may run one. Do not have it powder coated pink or highly polished stainless. Rather, try to keep the finish somewhat consistent with what the original correct* exhaust system would have been.

4) Correct Appearing. Everything not specified otherwise must be correct appearing. “Correct appearing” and “appearing correct” means: upon a cursory visual inspection by someone reasonably familiar with the year, make and model claimed, it looks like a correct* part.

Approved aftermarket replacement blocks are allowed (see list below). If you want to use an aftermarket block that is not already preapproved it is up to the individual to submit all the necessary information to the FASTRACES LLC so the block in question can be properly investigated. (part numbers, casting numbers, web site links, company names, phone numbers, etc) Raised decked and raised cammed blocks will not be approved. There will be a 560 cubic inch limit on all engines except the Ford 429/460 based power plants which will be allowed 604 cubes. If you run the stock production block there will be no cubic inch limit, but it will be up to the individual to prove it's legal.

3.01 The carburetor must appear externally correct*.
Internal modifications are OK. Carburetor housing must be the correct* housing for your application. The stamped part number need not be correct*. For example any 750 Q-jet can replace any 750 Q-jet as long as it externally appears correct*, but an 800 Q-jet cannot replace a 750 Q-jet, even if it does appear externally correct.

3.11 Gasoline as outlined here is the only acceptable fuel for use in F.A.S.T..
The F.A.S.T. tech inspector reserves the right to check gasoline at any time during competition. Gasoline is defined as a mixture of hydrocarbons only. The average dielectric constant (D.C.) for the hydrocarbons that compromises gasoline is 2.025. This is defined as a reading of "0" on the fuel-check meter.
3.13 Propylene Oxide, Nitro-methane, alcohol and nitro-propane are NOT allowed.


4.01 Cast iron exhaust manifolds are mandatory and must be correct*, have correct* casting numbers and be of correct* material. Under no circumstances will headers be allowed, including those cars that had headers delivered in the trunk.
Internal modifications are OK. Correct* appearing exhaust manifold paint or coatings are OK. Casting date codes are not looked at and are not part of the tech process.
4.02 Even if equipped from the factory with cut-outs, all runs must be made with closed exhaust running through the mufflers.
4.03 Exhaust systems may be upgraded to a maximum of 2.5" diameter head and tail pipes.
Exception: Certain Max Wedge cars left the factory with 3" inch head pipes, these cars can retain these head pipes up to, but not past, the transmission tail-shaft. Even if equipped from the factory with cut-outs, all runs must be made with closed exhaust running through the mufflers.
4.04 Mufflers must be stock looking in design.
No welded mufflers allowed. Maximum muffler inlet and outlet is 2.5”.
4.05 Exhaust pipes must exit in the correct* original location.

5.02 Valve cover spacers are not allowed.
5.03 Maximum of 2 OEM type gaskets under each valve cover allowed.


6.01 Camshaft must produce a correct* stock sound at idle. We all know what a STOCK cam sounds like! Factory cam specs will be taken into consideration when determining the correct* idle sound. 

Example: An Olds W30 or a Mopar Max Wedge car had large cams from the factory. They will not be expected to idle as smoothly as a 1973 400. Camshaft lopiness and smoothness will be teched with the engine operating at idle RPM and from the exhaust outlets. Upgrade to solid flat tappet or roller cam OK. Mechanical sounds from the valve train are not a tech item.

Note: The camshaft rule is under investigation, so that it may be better enforced. Currently there are no changes but the F.A.S.T. Board will be conducting various tests during the 2010 racing year to determine the best way to tech for this. During 2010 there will be testing of cars done at the track (during normal F.A.S.T. tech) to document engine vacuum, idle rpm, db sound levels, etc.. These test results will be used to better clarify, test and enforce the spirit of the F.A.S.T. camshaft rule.

11.02 The transmission must be of the same manufacturer as the car.
For example: an Olds with a TH400 could change to a TH350 or Powerglide, and a Chevy with a Saginaw could change to a Muncie or other GM 4 speed trans. Transmission casting numbers are not a tech issue. Internal modifications are OK.

15.01 All track safety rules apply and you must pass track tech.

When required by track safety rules, roll bars and aftermarket seat belts will not be cause for disqualification under the 'stock appearing' requirement in the F.A.S.T. rules. We require that everyone racing in the F.A.S.T. class maintain a stock image and appearance as best they can. Every effort should be made to integrate required safety equipment with a correct appearance. Careful shaping and placement of the roll bar tubes to hide them as best as possible and painting of the roll bar is one way to try and blend in the roll bar with the interior.
