Which engine is Cooler?

Tin,
Nice to see you still hanging around here, thought you were going to build a
FF Cobra ? Anyway, what about a newer Cummins Turbo Diesel...something different and cool especially for a old truck.

Ross,
I never left. You guy's talked me out of the Cobra, just too ordinary. The Cummins is definitely cool, but it weighs too much (I think someone posted 1000#'s) I'm really leaning towards the Viper..
