ProForm 750 vacuum secondary equivalent Holley? (Links for adjustment added.)

  My ProForm 750 vacuum secondary (With electric choke.) would be the equivalent what Holley carburetor? I've looked online, tons of info yet every time the direct info I want gets skipped. I'm ticked off and amazed at the same time, videos from Jegs, Summit and Holley soooo close, sooo much information. If I just knew?

When I ordered my Proform I called and talked to the guys at Proform and they said their carbs actual cfm is higher than carb states.  I would suggest calling Proform and they will give you exact numbers and may be able to tell you the Holley equivalent.

I am no expert...

There are seemingly millions of Holley carb numbers - but they aren't all that different (ie there are like 12 numbers for the one I have but mostly it's just different stock jets). Your Proform doesn't have a choke horn (right?) so that significantly lowers the possible matches. You're looking for an "HP" series carb I believe.

 Finding Quickfuel and Proform share parts helped sort out info searching. (Thanks Ron!) Much Holley info was kinda confusing as Q.F. and P.F. are hybrid and built to accept changes Holley assumes are fixed settings. In some of these links info is duplicated and some info seems to contradict but used a starting point you can jump to topics for ether vacuum or mechanical secondary setup/adjustment questions.   I did see Q.F. offers a "780" that is just like my P.F. "750" so possibly the same?

Yep, QF & Proform share the same parts. The QF SS series street carb is basicly the same as a PF vacuum secondary unit. 

The nice feature is adjustable jetting on the secondaries (screw-in jets) as opposed to the metering plate system that Holley uses on their vacuum secondary carbs.
