I wouldn't bet those Corvette manifolds won't fit on a Chevelle. We put a pair on Terry Penningtons 69 Camaro F.A.S.T. car just as a trial to see if they would fit and they cleared the sub frame (they were close on the steering but didn't hit) with no problem. You would have to eliminate the heat riser and get a little creative with the exhaust pipe bends, but it could have been made to work. I'm not saying the factory would have done it the way we were going at it, but there is still a possibility. Terry has a 67 Chevelle 4 speed car in his shop right now that's going to get a 375/396, and I'm gonna try a pair of Corvette manifolds on it just as soon as the engine goes back between the fenders.....
