I have a 82 chevy k10 with a 400sb when I start it up and let it warm up for a while sometimes as long as 25 to 30 mins. And I rev it up it backfires thru the intake. I put a new carb on it holley street avenger 770cfm and it has new fuel pump. The exhaust leaks a little on bank 2 in between the header and block. I have also put the timing light on it and its right where its suppose to be. This truck has been sitting for a long time before I got it
