Radar, it seems like going richer with power valve (sooner as vacuum drops off) and bigger squriters for the pump is making it better. Chevelle 292 Wagon, isn't there some kind of metal sleeve inside the stock intake that directs fuel flow? IIRC someone here opened up the stock intake to the Holley/autolite 2100 bolt pattern. He had to epoxy on the inside of the intake I believe. On my 1bbl intergrated head the bottom of the intake IS the exhaust manifold! On a 2bbl intergrated head, there is a metal exhaust gasket that forms the bottom of the intake. Jay
