Title: Buick 7042240. 800 cfm question
Post by: Mr.Pontiac on August 27, 2022, 09:00:27 AM

I took a lot of measurements and the idle tubes are set at .036 and idle down at .046 My concern is the main air bleeds in the airhorn is .070 but the main body air bleeds are tinny like .015, your book calls for .070. This yr. Buick was that the norm? Carb is going on a 462 Pontiac stroker motor. Any and all advice is greatly appreciated.

I would leave them at the stock sizes...
