just put top end on 383 stroker sbc and it idles high about 1200 rpm sometimes if i tap the gas it will drop but not all the time. i checked for leaks and timing both seem fine also on acceleration it back fires a little through exhaust

Check the adjustment of the choke and fast idle cam/pulloff

my choke is disconnected, not sure what the fast idle is but if its where it engages the throttle a little, its not touching.
