I've got a Rochester 2 Jet 2gc 2 barrel carburetor on it right now, it was on the truck when i bought it, and research shows the carburetor came on a 1975 Chevrolet car with an automatic transmission. Does anyone know what kind of CFM these carburetors flow, and how well they take to bumps and steep inclines? :confused:

Changing the intake would be necessary, but a Carter AFB would make an excellent choice.
For a 283:
Carter 9400s or 9410s
For a 327:
Carter 9500s or 9510s (both electric choke)
Carter 4758s (manual choke)
For a 350:
Carter 9625s or 9635s (NOT 9635sa) (both electric choke)
Carter 4759s (manual choke)
Modify the unit you choose by installing the special Carter marine/off-road spring-loaded fuel valves.
All of these carbs were produced PRIOR to 1985. I won't personally use or recommend the newer units.

Good carburetion is fuelish hot airThe most expensive carburetor is the wrong one you attempt to modify. If you truly believe "one size fits all," try walking a mile in your spouse's shoes!The Carburetor Shop | | |
