Holley Carburetor identification
I got a old Holley 4-barrel double pumper that has had the air horn milled off.
These are the only #'s I can find on the carb and the base plate.
12r-4770B
R-24
R-46
0643
7504 3
Any help would be greatly appreciated.

Re: Holley Carburetor identification
I am pretty sure everything on a 650 and a 750 interchange. The only difference is the mainbody. I would assume it's a 650, though. I havent seen a 750 next to a 650 to tell a difference though.
