Re: Tricked-out Chevy six cylinder engines
The 250 in my 66 GMC short bed . Equipped with a offenhauser intake and valve cover, hedman hedders. It had a holley 390cfm four bbl. but if you don't open the 4 bbl up the gas in the rear fule bowl turns to varnish and gums everything up. Ask me how I know? So I put a 2bbl Rochester from a 283 chev on it. Its backed by a power glide trans.
