Overheating issues with remanufactured 360

Sounds like the OP isn't really interested in fixing the issue, but FYI - my Valiant has an aluminum radiator, a 180 t-stat and a single large electric fan with no shroud and it doesn't overheat. It also makes over 500 hp and only has a 650 DP.

So ditch the shroud and fans and get a big 18" and attach it to the back of the rad?
