if its going in an olds then i would wanna put a olds motor in it. but it doesnt realy matter thats just like buying two different brands of water. some people say ones better then the other, some people say "waters water." me personaly though, am a chevy guy but i have an olds and want to put an olds 350 in it but like they said before, parts are cheaper and everywhere for sbc 350 and just as good. how much bang do u want for your buck??
