Same here. I love my sb chevys. When I started messing with the 3800 series, I thought I knew what I was doing, but no. GPF has taught me so much. So what electrical problems have you been having?
they had to replace the fuel purge solenoid connector at the underhood main fuse block as well as the MAF connector at the same location.
Felt like the junk had a th400 w/ a stall and atleast stage 3 if not full race shift kit in it.
