I've been trying to find a cure for my 2.70 60 ft times leaving at 0 boost. (can't hold any boost). Swapped out noisy powermaster with hydroboost, and I went from 1200 to 1600 rpm that I could hold on the footbrake (still no boost). Replaced front pads and rear shoes, bled the brakes 3 times with a mityvac pump, and I still cant hold any boost on the foot brake. Is it possible that the converter may be causing my problem, as in the car has the wrong converter in it? The car has had tranny work done in the past by a previous owner, but the guy I bought it from didn't know what had been done. Car has boxed uppers and lowers, rear air bags, and m/t et DRs. I think if I can launch with some boost and get a decent 60 ft time I could knock off a second in the 1/8th mile. Any help appreciated.
