anybody ever use a proform?
 

as anyone used a proform street seris carb if so pros/cons? Does it work better then a holley or demon? Thanks

They are all just bonified Holleys with different names , demons , quickfuels, proforms etc, they all act and tune just like a regular holley and most take over the counter holley parts.
I used a proform center section on my Holley 750 double pumper carb I had milled the air horn down on, swapped it out with the proform contoured venturi center section and it picked my car up 2 tenths, not bad for 10 minutes work and 90 bucks.

Holley now offers a "cheap" HP style main body also.
Same price as Proform.
