I don't think a 318-4 manifold is gonna be legal. They were 1978 and newer and were Thermoquad only. I think you'll need a manifold with the "little AFB" pattern.
I believe Paul Wong and Bill Bushmaker have experience with these engines. As Jeff said, if the Edelbrock is legal, that will help a lot!
