305 Exhaust manifold vs 350 any Difference?
Is there any difference between the 305 TBI exhaust manifold and a 350 TBI exhaust manifold? Seems like they would be the same to keep cost down for GM.

Maybe he meant TPI? If so there have been a few threads about exhaust manifold difference I'd search it out.
