Pro Form main body vs Holley HP main body

**f100cleveland** · 02-15-2005, 08:13 PM

Hello, I have a 750 Pro Form main body and have a chance to get a 750 Holley HP main body. Which one would be better? I'm guessing the Holley HP would be of better quality but wouldn't have the adjustable idle air jets. Which one would you guys recommend using? Will the HP flow any less than the Pro Form?

F100.....both bodys are fine pieces and will require the same tuning towards your application.....There will be no atvantage in either one.........The Holley if its the HP should have the screw in bleeds unless its a really old-first design....Jesse

Ok, the list # is 80528. Is that the old original style one or one of the ones that has screw in air bleeds? I know the 80528-1 has screw in air bleeds but can't find any info on 80528. Thanks
