Dave,
I would try crisscrossing the spark plug leads on the distributor. This is
an easy test to see if you have the timing out by 180 degrees. For some reason
every time I rebuild my race engine I get the timing out by 180 and I get
backfires and flames out of the exhaust. If you are lucky this will work
otherwise I would get a dial indicator and degree the cam per the instructions
in the competition manual. Good luck.
