I'm putting together a 511 hemi, going to use a rat roaster. I know there are better manifolds, but this is what I'm using. I'm after the old school look. I've been told that many years ago there was tech-tuning info printed in a direct connection book. I'm after that info. I understand that the manifold needs a few dams epoxied in it to help with fuel distribution. I'm running the dual quad top plate. Thanks again.
