Holley carb I.D.

Yeah the choke horn has been milled off. It is a double pumper with a 1 11/16 base and the main body as well. Downleg boosters and a casting # on the main body 6R 3752 B. Front plate has 8397 and 47791 below. Rear plate 6543 and 47791. Thinking it is a 750 but would like to be sure to order a kit. Thanks

Since a #4779 is a 750 Holley, I think you made a good assumption...

Just match all the gaskets and parts before you use any
And keep the old parts and stuff till you have it running well

Here is a link to the holley tech library carb numbers pdf, there is a R4779 and an R4779-1 listed. It has plate, bore, cfm, kit numbers, etc.

Thanks Guys, Kit on the way. Going to swap it with a 3310 and see how it likes it. Are we ever done? Nope!

Got the 750 double pumper on and the seat of the pants test drive seems better. The instant throttle responce from idle to WOT is awesome. Specs are 72-76 jets 4.5 PV F&R 31-35 squirters. Going to go play with it and see what happens.
