Probably a Dumb 318 Question

If you want Coyote type power out of the 318 your best bet would be to build it to the specs of the 70’s T/A race motors, which were 305’s, mopar destroked the 340, but you could do similar with the 318. This would bring the power up to the 4-7+K RPM range, depending on the cam. Not very practical for street driving.

As others said not apples to apples comparison. A more apple to apple would be the Ford 4 cam or Cosworth DFV, with are both 60’s tech, gear driven 32 valve OHC, with 500+ HP from about 3 liters. This is where some of the tech for the coyote stems from. But way out of reach for the average person.
