couple problems

Hey all. Well im having some issues.
Truck is an 86 chev crew shortbed stepside with 38s so my motors always under load
the engine.
400 small block chev
.30 over -5 cc dish pistons 268h cam vortechs performer edeljunk 600 one of my problems is i ran my truck down the track and when in 3 rd gear after i let off the throttle (sm465) it backfires from both pipes but only one time....? 2nd is i noticed if i wot in 1 st not granny it blows smoke but i cannot tell if its unburnt fuel or oil burning off. Im thinking the 600 edel is not enough airflow? Running rich as its sucking more fuel then air? Any ideas?
