In the southeast there is a “fuel†series 525. Look at fuel rules, call Kenny Lamb, he wrote the rule and was the original “series “ rebuilder. Then Hendren got in the game and some “mistakes†(rod,piston height,etc...) took place, so rather than say no those motors are wrong, fuel and a lot of tracks just adopted the nonconforming 525. So in a nutshell in the southeast a 525 does not always have to meet GM specsOriginally posted by let-r-eat View PostA 525 that doesn't meet GM specs isn't a 525 is it?
