Hello all,
I, too am suffering from the 440 backfire problem. Mine seems to be hit-or-miss as to it coming from the carb or the exhaust. I have tried all the standard stuff for resolving the issue (plugs, wires, cap, rotor, check fuel pressure, timing, heet in new tank of fuel, and even swapped the carb for a known good unit...) On the note of swapping the carb, when I pulled it from the intake manifold, I noticed a "hole" (more like a burned through spot) about 1/4" - 3/8" in diameter on the intake plenum floor on the drivers side? Is this normal for a Dodge? I am a Chevy guy and rebuilt a ton of small and big blocks, and haven't ever seen anything like it. Is this part of the egr ports, or have I found a huge contributor to my backfire problem? Any assistance you can give a confused Dodge owner would be greatly appreciated.
Thank you,
Chris
