Here's am interesting one. This LS1 has been swapped into a custom widebody S2000 here at NOPI. The owner purchased a wiring harness from another company a year ago, but after numerous phone calls and sending the harness back to be checked the engine still wouldn't start. Dr. Tweak offered to have a look at it and with a borrowed multimeter started checking it pin by pin. Less then an hour later he noticed something wrong, swapped a few pins around and the LS1 roared to life! #drtweak #ls1 #s2000 #tweakd #tweakdperformance #importmuscle
