I just recieved a 650 double pumper carb from my cousin for next to nothing. I am running a 355 with a T-56. The engine has dart iron eagle heads, a pretty wild flat tappet cam. My question is, is what proform kit do I need to convert my holley 650 dp, to a 750 dp? Can I do such a thing? Would my 650 DP work fine as is? If I can convert over, what is the part number?
Thanks guys,
Zach

your 650 is good to go cfm wise, but there's always the holley 750 HP mainbody to upgrade to if you wish.

My Holley 650 to Proform 750 mainbody conversion machining issues existed in the Holley throttle plate.
One word of caution: If you have 2-corner idle, make sure the mainbody has small air bleeds for the secondary idle. I don't know about the Holley HP mainbody, but my Proform didn't have those smaller bleeds included. Others who have purchased one recently said they were in the box.
