Current big project, remove everything from the firewall, clean and paint the front frame section, bedline both sides of the inner fenders and firewall that shows and repair the harness. Once that is done the 383 is getting dropped back into it. I had a a rear main seal leaking on the fresh 383 and with the front clip and headers off already doing the steering gearbox and harness it was only about an hour job to pull the engine again.

What the 383 sounds like with a Q-Jet on it and the open tri-ys off the Express van.

Currently adding flex fuel sensor and fuel pump hotwire wiring into the main harness as well as redoing my electric fan harness. Also adding an a/c pressure transducer. This 97 is running on a Blue/Green terminal 1 meg 2005 DBC 6.0L Express PCM with a 2005 Mexican GMT800 L31 5.7L vortec based engine calibration. The Racetronix hotwire kit was an old modification that feeds the fuel pump directly from the output stud of the alternator through 10 gauge wiring and a 30 amp relay as well as geounds the pump through a 10 gauge ground wire. Was necessary for the 340 LPH fuel pump upgrade to support my ~500 hp 383 on E85. Those 6.2L Raptor injectors on the marine intake get thirsty on E85 around 5,000-6,000 rpm.
