The kicker is..... at the end of the episode, they threw in a joker, a tired, smoking, almost stock low compression 440 with log manifolds.... and a single turbo.
It made 514 hp, competitive with the other two engines, but it also made 660 ft/lbs of peak torque, a hundred more than the bbc.......
And 1.5 ft/lbs per cube.
Just think what could be done with a fresh engine built to exploit the turbo.
