Goopie, I suspect the difference in heat generated by the three different engines you test drove has more to do with insulation, timing, carb setup, ventilation than the engine itself. My buddy runs a Roush 427 (R or SR, I don't know) and the heat was so substantial he took extra steps with ventilation and heat blocking to keep the cockpit, of his CSX, within reason.

One time, when I was trying to dress up things under the hood, I removed the very thin layer of insulation between the headers and the foot box. My thinking was, that was SO thin, how useful could it be? Whoa, bruddah, DO NOT remove that insulation!!! It may be thin but man what a difference it makes, night day.

As far the 427 cid goes, thats out to far for my liking. I'd stop around 408 or so, max, just my opinion. By the way, my buddy with the high heat Roush 427 recently replaced a blown head gasket, out of warranty.
