Seems like keeping track of all that plumbing and wiring could get overwhelming. What does your punch list look like?
The wiring has been simplified dramatically with the ECU set up from Chevy. I have a vehicle speed sensor to wire yet and a pink ignition wire to tell the ECU that it is go time. The AC will need some thought since it will have a new compressor (fittings mostly). Of course it has hydraulic brakes and steering, but I ordered a PSC high volume pump with the accessory kit and I don't know how that will do. I'm also considering a different cooler for the power steering. I have to find a spot for the reservoir.
The PCV system is something I will need to sort out. This one is tricky since I want to keep a PCV system, but want to avoid the valve coking issue the Gen 5 LT4's seem to have. The Corvette guys have gone through this already so I have a plan.
The front accessory kit is the biggest unknown. I might have to move things depending on what is discovered.
The dry sump is a cinch. It just involves a few hoses and a tank.
And, I am spending a pile of time on wiring in the cab: radios, displays, charger ports, heated seats, inverters, plasma rifles, etc.
