Default carbs

hey cepx11 thanks for quick answer. stock 750 holley comes with 75 square with 2 power valves, so if i remove the front and rear power valves and step up 8 jet sizes (as recommended by holley and quick fuel), then i should start jetting at 83 front and rear. i got the carb from my buddy already done and i only made a few minor changes. he had it jetted 82 in the front and 84 in the rear.i changed back to a front power valve(3.5) and lowered front jets to 74s(down 8 sizes). i really thought that this would help prevent loading up whild driving in the pits. i asked on the forum about the power valve vs no power valve for drag only car and the views were about 50-50 for and against, so i felt the safest way was WITH the power valve in the front. does jetting sound right to you and i guess your thought is to NOT run a power valve. i really appreciate your input. i still have time to go NO POWER VALVE in front. im going racing on sunday thanks art
