My overheating issue solved
Issue was retarded timing, but also need to add fuel Octane boost. The engine is an LS7 at 12.5 to 1 compression, wants more than 94 Octane. Retimed at 4 d BTC like supposed to be and then added 104+ and I can keep it at 180 degrees moving, and while in traffic I can turn on the electric fan to drop it from 210.

4 degrees is still a little on the retarded side. Reduced timing means less NOx and CO, but isn't necessarily best for the engine, fuel milage, or performance.

Everything got swapped over, had to build a bracket for the fuel pressure regulator, modify the throttle cable bracket, rebuild some fuel lines, pull the screen wiring and mount the new one. So far...
