Ok so another snag with this motor. I put a used 306 block with new pistons, new afr 185 heads, used trickflow track heat and a b 41 cam. Ive been running it a little and it sounds like a growling noise from the intake. They are used lifters from my old motor but they seemed fine in my old motor.

Could my lifters be making a noise like that? It sounds kinda rough. Not smooth like my old motor. I cant find any info on this problem. Just seeing if anyone had suggestions before I order new lifters.

Thanks guys

had a few different cases of this with various vehicles coming through my shop. 90% of the time, the MAF was the culprit. run codes.
