I have a friend interested in racing his car this year and I cant find the rules to pass on to him? Any help
what races can this car attend Heres the deal. 1969 gs stge 1. The car came with a 400 block but that is long gone. Externaly the complete engine looks exactly as a 430 or 455. He has a stock looking 455 in the car but the numbers say it should be a 400. What are his options? Im sure the car is in the 12-13 sec range. Thanks. Finding a 400 is near impossible because all the big cars had bored 400 that came to 430 cubic inches. The replacements pistons tell you to bore the 400 to 430 cubic inches. He wants to participate but why put a 400 that can be borred to 455 when 455 engines are plenifull?
Chris, A bigger bore size and an extra 55 or so cubic inches is not going to work in the Pure Stock race. (They P&G engines for CID violations) With the extra cubic inches, the car would fit into the F.A.S.T. class. Where using a 455 block would be legal. F.A.S.T. rules can be found HERE
Chris I have a 400 block that is not bored to 430 specs. it could be had cheap. it is all cleaned up and was bored .030 and then stored..this was a replacement block and has never been decked or stamped with any factory codes or serial numbers. Bob
