I just got my 77 280z 2+2 running after a head/ head gasket swap. It now has an N47 head on a N42 block. I let it run for about a minute, then tried to turn the distributor to help it run smoother. I was shocked when I grabbed it. I was wondering if this was normal, because I don't remember having that problem before the rebuild... Is there anyone that knows all of the grounds and where they are supposed to be in the engine bay? I have the manuals from xenon but I still am obviously doing something wrong. also, I took the car for its second drive on the fresh head and I randomly lost power twice. The first time I just started the car again, but the second I had to get a jump from mom's car.
The wiring harness is a mess due to the P.O but it wasn't giving me problems before i switched heads.
Also: my temperature gauge is not working anymore (just in case this also is a grounding issue)
