FYI, I bought the same radiator as the one you're using in the frunk and was very pleased with the build quality for how cheap it was. The only problem with it is the pressure valve on the cap is too weak. It will release pressure around 190 and continues to drip even when the car is cold. I'm going to weld it closed as it's not needed for my situation. I also plan on installing a radiator hose with a cap built into it at a high point in the system to help relieve air pockets.

I have a major setback, I rotated the engine before I bolted the transmission up but now with everything assembled it won't rotate....ugh. I'm going to pull the transmission off tonight and see what the deal is. Did any of you guys swapping Audi V8s have a similar problem?

When I first mated an AUX (40 valve) with a Boxster 5-speed transmission I had that exact problem. It required a small spacer between the engine and transmission to provide enough clearance for the flywheel/clutch.
It's been a few years, but I had these links bookmarked:
