40 years ago i put a 351 in a 1966 mustang using stock exhaust manifolds.needless to say i ran into the same problems then that everyone is running into now.now,40 years later has anyone come up with a solution to this problem other than a torch and a ford hammer?i dont want big tube headers,700$ headers,or any solution that almost fits.you would think there would be a stock exhaust manifold that would fit but we never found one.so i ask the younger generation,or older, what are you doing for this problem?
