I'm like you, I like Edelbrocks. However, since this is mainly a race engine I think I would look at Holley. As much as I love the Edelbrocks, I honestly feel they are more of a street carb. I have a 460 Ford that will someday go into a drag car, and a Holley will go on that one.

As for CFM, etc. you might want to talk to a tech at Holley and give them all your specs and see what they say.
