For everyday driving I've bought a nascar type C & R alum rad with heat exchanger--it puts the
oil temp where I want it and I think it will even be acceptable for a few hot laps at St Louis, Road America or the other road coures
But if its in competition, My son Corey will be driving it on the road courses and I'll drag race it--when and if we go to Bonneville we'll both take a turn
at the 200mph mark
