@gavinmgrant My car had a built motor when I bought it. They spared no expense, Comp 278 cams, forged internals, dished pistons, aluminum Cobra block. I had some fuel issues after I had it about a year. When it came to connecting the wiring harness, they wire nutted the fuel pressure regulator wiring, left a bare ground that bounced around and eventually blew the PCM fuse and took two butt splices and put them on the pins for the IAC. I don't get how they spent ten grand building the engine and then BS'd the harness together.
