Big Block Edelbrock limitations.

Actually no he is not. I gave you a legitimate answer first. You can go look at the flow numbers and get a good guesstimate of the HP level they will support. That is exactly why I pointed you to the flow numbers......because of all of the directions this thread had gone. Just because my answer required you to do a little work doesn't meant it was not an answer.
You are right. I apologize. I looked at the flow on their website, and used one of the Wallace calculators, and although I am not sure of the VE, I took a guess, and it seems like the heads may not be my issue. Is there a standard value (or something close)for the VE of a street style engine?
