So I picked up a 325HP 1967 400 XX motor today. Never has been bored. Was complete with carb, pulleys, brackets, etc. It has 061 big valve high compression heads(I know I need to tap these for screw in studs). I was wondering about a few parts. Are the 4-barrel intake and the carter AFB 4-barrel any good or worth any money to someone who needs correct parts? Also it has 9779032 9779328 1968 GTO Exhaust manifolds on it. Are they any good, or would they just be good for someone who wants correct numbers on their 68?
