Just as an update, did get the Wizard radiator from Chris and installed it. Quality item and in conjunction with a custom aluminum shroud to force air thru the radiator my water temps have dropped to 200 on track from 230+. One caveat the radiator is thicker and it pushes into the radiator hose into the power steering pump pulley. I had to saw off the nub on the pulley to gain clearance.
With the temps down I was able to run the powertrain harder at Texas World Speedway last Friday. The track was partially wet and had some occasional mists so traction was limited in the corners. The LS6 would spin the rear tires at will in 3rd gear on relatively fresh Hoosier A6 295/30/18 tires.
The car was almost able to keep up with a chipped new GT2RS - yes, the real deal - on the front straight hitting close to 155mph. For points of reference, the GT2RS is rated at 620 hp stock, with chip probably closer to 700 hp. My car is lightened and the motor is probably around 400 rwhp. When I ran the K27/6 at 310 rwhp I could only touch 140 or so on the front straight.

Can you post a pic of the radiator clearance issue between the powersteering pump pulley and the hose?
Thanks,

By eyeball the Wizard radiator is about 1" thicker than stock
The ducting dovetails nicely into the AIR splitter I have. The dovetail "U" shaped on both sides to stiffen the flimsy stock rubber vertical shroud

BTW, you can get a hose from the local auto parts store that makes a much tighter 90. Your hose is a standard 90. They have (which you can cut down) 90's that make the 90, but angle the hose back toward the radiator, then straighten out. Effectively letting the hose make a 90, but come back (tightly) to parallel against the radiator.
Other than that, did the radiator fit into the stock location or did you have to further modify?

The Wizard fits into the stock location without any mods. It has done the job but if Eric at TPC comes out with his radiator soon that puts in the inlet and outlets at more optimal locations I will probably switch over
