Hey fellas, I just had a crate lt1 from jasper put into my 95 z28, it runs like a champ, but since the new engine was put in it has been popping in the exhaust. The mechanic that did the swap says he thinks something is broken in there, like rusted off or something, but it was just as smooth as could be with my old lt1 even with a spun bearing. I have read a few threads about running rich. Everything is completely stock except the motor.

Thanks for any help.
