I have a 79 chev k20 that I use pulling a gooseneck trailer. I have had a problem with the engine losing power and exhaust gunfire when pulling hard at higher speeds. It gets worse when the engine is fully warmed up and pulling hard. I have checked the cylinder pressures and they run 115-125psi, so the valves seem to be good. Timing checks out ok and the advance is working. Is it likely the quadrajet is causing the problem? Anyone out there who has had the same problem?
