On a 650 DP Holley, what would the final CFM rating be after the Proform Main Body is installed? I've seen a few different numbers, but I'm looking for something concrete, not just an advertisement. I know it's been hashed about a few times, but I couldn't get the answer I was looking for in a search.

When I bought mine I called Proform and the tech guy told me that the 750 main bodies flow 830cfm on average.

That is the info I am looking for. Calling Proform was my next step. Thanks alot, 350.
