Re: [Chevelle-List] 780 Holley Carb ID

[Richard Milkiewicz]

Donnie, according to my Holly bible, it's a 750 c.f.m. And recommended for 350 - 455 C.I.D. engines. Non-emission, vacuumed secondary, manual choke. Model 4160.  Dual feed and center hung float bowls or side hung. If it's original it is not a double pumper. It is identical to the 4150 in appearance but the 4150 is a double pumper and cost more to make because it's a hotter carb and operates differently. It also has a secondary metering block where the 4160 has a secondary metering plate with built in orifices. They were used by American Motors, Chevrolet, Chrysler and Ford as original equipment. They are just as high performance oriented as the 4150 and can be converted to the 4150 features with a kit. I can't find OE # 3878261. If it is in fact for sure a 780 CFM then it's an elect. choke, duel feed center hung bowls with vacuumed secondary, 1970 - 72 350 - 455. Hope that helps you out. Either way, it's a nice carb.
