The Proform main bodies have sculpted venturis, no choke horn, and adjustable air-bleedsFWIW, when I bought the main body for my 650 dp carb, I read that you could gain 25-50 hp. I thought Yeah right, but I tried it anyway because it was only 99 bucks at the time and it would bump me up to 750 cfm. To my surprise, my car picked up 3 tenths and a little over 3 mph in the ¼ mile right off the batthats probably about 30 hp! Then I started tuning and it just got quicker from there (I carved a couple more tenths off over time).

sweet man! so im assuming that each of the main bodies will increase flow 100cfm? because it doesnt say so on their website...if i was to use one it would be on a vacuum secondary holley though, but im not sure if you can change the jet sizes on a holley metering plate without extensive mods....i guess i would be flowing 850 cfm by adding a proform body to a 750 carb? think that might be overkill though??
