Gary, for my 2cents I was having alot of cooling issues with several stock type radiators including one from a 383 A/C Barracuda. I'm sure part of my problem was the state of tune. However I got a Summit crossflow radiator #SUM-381425 for $189. I spent another $90 at the radiator shop and got it customized some. It cools waaay better. If it gets hot at the drags all I have to do is drive it thru the pits once and it cools down. I do believe I'll need a shroud or preferably an electric fan set-up. I think it's a much better bargain than the BeKool $800 set-up.
