Just got a 650 DP and was wondering about the proform mainbodies. Anyone running one and how do you like it?

Yep. See sig.

Didn't notice a huge improvement over the 650. Kinda miss the choke when first starting it up, but at the track isn't an issue.

Nice piece, and IIRC they flow in the 780cfm range.

I installed the Holley PV blowout kit into the ProForm, since my stock base wasn't equipped.
