For a car, wouldn’t the best engine be the one with most horsepower per pound? I would think a tank engine would be low on the list.
Wouldn’t it be better used in a pickup?
Your answer is yes, but in this case they were looking for the image value of this huge motor.
But you can go 300 mph with a Toyota six banger

I love it the way it is
Torque is more important... Just put taller gearing under it, it won’t phase it.
