Exhaust manifold
What is the correct numbers for a 1966 corvette exhaust manifold. Arethere two different numbers for each side?
Can a 1965 manifold fit on a 1966 327/350 hp

Yes, but you'll have to change the front exhaust pipe; the '65 used 2-1/2" pipes all the way to the 2-1/2" outlet on the manifold, and the '66 used 2-1/2" pipes that necked down to 2" at the manifold. All '66 small-blocks used exhaust manifolds with 2" outlets.
