i've got a 385sbc its all forged with eagle bottom end dart heads lunati voo doo cam installed straight up.the top end consists of an edelbrock air gap intake 770 street avenger carb and msd hei billet distributor. my question is this when i go to time the car it doesnt want to idle under about50 degrees and when i do back the timing down to around 34-36 (with the vacumm advance unhooked) it starts to run poorly and backfires through the carb wehn you hit the throttle.any ideas on what it could be.the motor has a aftermarket fluid balancer and cloyes timing chain cover with aftermarket pointer.think the timing marks could be off? could i be one terminal too far clockwise on the distributor cap with my #1 plug wire?is there any easy way to double check to make sure the timing marks on the balancer are right?
thanks for any help!!!!!
