Cab, owned this car for over 20 years and this combo for over 16 years. 6.5 psi on dyno pull after dyno pull. Mallory comp 180 pump with 3/8 lines. Fuel/air is a tad rich at 12.5. It is not lacking fuel.
I think this car is maxed out on MY definition of a street car. Pump gas, power steering, power brakes, nice stereo, full auto valve body, 3.73 gears. I know that this combo is not to far away of failing a block. Just a bad tune up or a broken valve spring away.
Oh by the way this is a rotisserie restored car that has won 1st place 3 years in a row at Mopars with Big Daddy and in 1999 or 2000 at the Hot Rod magazine Power tour, in a sea of red Camaros, won "Best Street Machine, Non Tubbed"
I am always chasing the next tenth, but as stated, the lighter wheel combo and the electric water pump/fan and even removing the power steering belt did nothing to improve ET or MPH on this car.
