Re: Carberator adaptor
If you have an EPS manifold, then it is not a spread bore manifold. The EPS is a square bore manifold. Edelbrock does not list an EPS manifold with a spread bore flange. The only spread bore flanges they offer are the standard Performer(2101), the Performer Vortec(2116), Performer Air Gap(2601) and the Performer RPM Q-Jet(7104). If in fact you do have an EPS, I do not recommend running a spread bore to square bore adapter. If it's a standard Performer or one of the other manifolds I listed, they should have holes for both square and spread bore on them. I agree with the need for a carb insulator, but DO NOT use a flange adapter.
