Re: any help please
Formula is a style package like Z28, GTA, RS etc. The 350 TPI will be an L98
Checking the VIN number can tell you if the car originally had a 350 or not from the factory. That doesn't mean it still has a 350. It could just as easily be a 305. Checking the block casting number can tell you if it's a 305 or 350.
Depending on the transmission and diff gear ratio, there are 2 different 350 Formulas and 4 different 305 Formulas.
