Just out of curiosity, Jim PA, do you agree with '72customdeluxe? For example 2 motors both making 400hp.

Again I am not a motor builder nor have I installed either of these motors in my truck, but I do have a genius level friend and we had a discussion a long time ago about the new LS motors. As I recall we were comparing why a motorcycle motor makes more power on less displacement and runs on pump gas. I think that was the convo, anyway, he said the problem was heat dissipation. The newer gen motors run way cooler therefore more efficient. I assume that will play into '72customdeluxe's statement. If I am wrong please chime in.
