Fabrication of a 2 Barrel Carb Adapter for a 4 Barrel Intake (Part 1)
By Mark Strickland
The Factory computer fried and with most of the Wiring and Vacuum hoses gone I figured this would be a good time to upgrade the intake system. The factory carb was a Carter YB-1A (1 barrel carb). I replaced the Factory intake with an Offenhauser 4 barrel dual plane intake. This means there are 2 runners for each port (cylinder). I found a good (new) Holley 350cfm 2 barrel carb and used a standard 2 barrel to 4 barrel adapter plate.
