Help from DCOE owners (archive)

I've got 40 DCOE's on my 74 2002. The engine's had some work done on it. It has an E21 head, 300 cam, headers, and 10:1 pistons with good compression (170 even all around). Just rebuilt the carbs. Good thing is it still runs and I have no parts left over. Bad thing is I still have slight backfires on throttle between 3k and 4k RPM. Runs good WOT, and then backfires like made under load coming back down the RPM range. Idle is good and I have synched the carbs. What could be causing this? TIA
