The thing about the L98 motor is that it is the old style 350. The parts are the same no matter what you buy them for. You can get the things cheap if you just say its for a 91 Z28 w\350 instead of 91 Corvette. We can hook you up and get you going. So are you buying the car from your mom or does mom want more ommph and asked you to do something about it?
