[MKS427]

There are many ways an engine can perform, low end torque or high end power. You really need to define your driving or racing parameters to make a decision.
If you are going road racing, a Coyote with a dry sump may be best. Not enough horsepower, supercharge it.
I personally run a 351W based 427 Dart, 572hp/585tq. It has a hydraulic cam, performer rpm manifold and is very streetable with EFI. Now that I have 6000 miles on the car, I am getting comfortable with the power and would welcome more. Keep in mind, even with 100 series tires, losing traction is effortless below 60.
I like the sound of the 500+ inch FEs, best. They are pricey and I cannot speak to their performance first hand.
Good luck,
Mark
