318 Motor, please help

Welcome to the site !!! As you already can tell, many here will post what's not their personal preference as the problem... LOL. I've owned (and currently own) eddies, Holley's, bbd's, and all of my cars run really good. I'm glad you found the fix, that is always fun and rewarding. I'll throw out this, though, you might even like it better if you go up on your power valve.

Could not agree more with this post. Wish I had said it.
