Does any one know of any good reputable carb rebuilders for racing q-jets. I have asked on other racing message boards and have not gotten any responces. My car has a .040 over 350 flat tops, solid cam, 1.94/1.50 valves, 58cc heads w/approx. 11.82-1 compression, cast iron intake,headers, and currently a Holley 4412 500cfm two barrel carb but we can run a stock factory 4-barrel next year, and i turn almost 7000 rpm on a high banked 3/8 mile asphalt oval. Thanks 71
