Backfiring when back driven
I recently replaced the intake and exhaust manifold, carb and the mix on my 300 with a Clifford 6=8 and the Holley 390 carb. The timing is set to 6 off TDC and the truck runs great. However, when ever I get off the gas after a quick acceleration or am coasting down hill the engine backfires like a mad man and seems to be back driven by the transmission. This only happens with its in gear. Could this be a vacuum advance problem off the distributer or is there something else that could be causing this problem?
The truck is an 82 F100. The transmission is a 3 w OD on the floor. The transmission was just rebuilt and the engine has 230,000 on it and is still as strong as ever.
