yeah that would be a great matchup, but if we where talkin about derby motors id have to go wtih the 318 Mopar. Try running the other two blocks red hot and they will not run and fire up as well as the 318. The 318 handles the heat amazingly, another main reason why its hte most used derby motor. Can run without water and oil longer then most any other motor
