Need some suggestions here, I have a rebuilt 350 with flat top pistons, edlbrock performer cam and intake, (yea I know the cam sucks, but that is what it has) 350 turbo tranny, 456 gears in 3/4 ton axles, 35inch tires. New distributer, wires plugs, has the original quadrajet carb, This thing is a dog, seems like it is always behind trying to catch up when you nail it. Its a dog , was expecting to a least break the tires loose with little effort NOT. Any suggestions to what I could adjust? Have played with the timming, not a big difference, timing is sitting a 9 right now, could the carb be causing this? No snap at all to the motor, any suggestions would be appreciated, thanks for your time.
