Are both carburetor setup the same? PV and jetting? If not.....
The fuel mixture looks too rich. Reduce the jetting size or increase the power valve to
a higher factor to prevent it from opening too soon.
Also, look for leaking needle and seat in carb and excessive fuel pressure.

You have Holley 9375's.. the faint stamping below the "9375" ( as though you were reading it right side up) is the date code

not sure if i can do that with my extension pipes,,,as they are wet.....
i guess ,,i could make them dry dump water out another way ,,,but would the exhaust extensions and tail pieces in transom get to hot????
unless i make new extension pipes and make them like headers...double walled...that would be a fun welding challenge
thanks for advice
