OK I am in need of knowledge.
I recently replaced the heads in my 383 with a set of Eddy RPM heads. I also added new plugs and wires, as well as a used 750 Mighty demon carb which I went through and replaced worn pump and gaskets.
I have gotten the car to idle good but anytime I give it gas quickly it will backfire through the carb and die if I don't immediately let off.
I put the old carb back on and got the same problem. Right now I am running open headers and have 76 primary jets and I think 80 secondary jets. Any ideas? I am worried I may have a valve being stuck open.
Put it at TDC and the rotor was point at #1 so I know it is not 180* out. Its not drive-able at all as it pops and bogs almost all the way through the rpm range.
