Turning back the clock
The Hemi is being picked up AFTER it has already been run in on a Dyno....not for max HP, but for exactly what you mentioned above.....just no crank trigger dual plug ignition or me being there. IF I can be there.....we will likely skip the Flash Hemi in the mule mock up and I will just mock up the crank trigger wiring with the dummy block in the mule.
I am a big fan sorting things out pre paint....plug out....then plug into the fresh paint.
