Triple two barrel carburetors
Stock jetting for the 348 with stick shift was , Front carb,.060, center,.063, rear, .061. With the auto tranny, Front,.060, center, .060, rear, .061. I have ha d good results with .061 front to rear. I have heard that a fatter jet in the front for high performance would be a good idea because under hard acceleration the front cylinders would be lean.
