454 Exhaust manifold flange size question?
I am in the middle of swapping in a 454 from a 78 Suburban into my 70 3/4 ton. I am re-using the manifolds off the suburban, but want to build my own 3" exhaust. I have searched all over the web and cant seem to find what size the flange is on the manifold. Any help would be appreciated.
