| PROFORM carburetor main bodies rebuild a tired Holley-pattern carb from the core out. The line covers Holley #4777 650 CFM, 750 CFM vacuum secondary, 850, 950, and 1050 CFM double pumper models, plus 750 and 1050 CFM 4150 bodies and a Holley/PROFORM/QFT 750 CFM body machined for alcohol. Each is CNC-cut for a direct swap onto the 4150/4160 platform with no match-porting. When the castings are worn past a rebuild kit, the main body is the fix. |
