I recently changed the timing on the challenger (440, late model engine with large cam). It was set at 17* initial and all in at 38*. It ran rich and a little rough.
I now set the timing at 13* and all in at 34*. The car runs much better but I am maxed out on the distributer curve.
My problem is now I either have the gas boiling and flooding the carb or heat soak.
The car would start fine with the higher timing.
So does the timing have anything to do with heat soak or boiling over?
I did put in a new mechanical fuel pump from mancini, if that makes a difference.
Old one was mechanical also.
