Next up, cooling system.
I had quite a few ideas on how I wanted this to work, but here's the basic concept:
Ordered a radiator that roughly matched the stock unit, but was dual pass, passenger side inlet/outlet, to better fit the LT4 coolant layout. Cut the barbs off and welded in -16 AN top and -20 AN bottom. I still need to add a -6 ORB fitting for the expansion tank. I bolted the Chevy Volt cooling fan up after a tiny bit of clearancing work.
I then machined small aluminum blocks, drilled/tapped them, bolted them to the OEM Aston AC condenser and then welded them to the radiator.



The stack is very close in overall size to the OEM setup, and fits roughly in the same place. The OEM isolators won't work, but the bolt-in radiator "crossmember" that came on the car was close enough. I cut up some hockey pucks, added rivnuts to the crossmember, and bolted the pucks in to isolate/locate the bottom of the radiator. It's not stupid if it works.

Next up was the oil cooler. The car had a stock one that wouldn't fit my needs well, so I picked up a basic aftermarket bar/plate unit that was similar in size to OEM. The OEM until also had a duct that routed the hot air out the bottom of the front undertray, so I figured I'd copy that design as well. The stock piece was plastic and a little fragile, so I made the new one out of aluminum, and bolted it to the radiator crossmember. The upper mounts for the oil cooler mount to the crash bar (more rivnuts) and the lower mount is the fabricated crossbar you see in the pictures below.




The oil cooler hoses are also routed. I'll add some heat protection and chafing protection/routing control later, but they're in the correct area at least.


This last remaining gap is where the heat exchanger for the supercharger will slot in. Hopefully I'll have that finished up next week, then build the radiator hoses, finish the power steering lines, and start sorting out dry sump tank mounting and supercharger reservoir/hoses.
