A good 427W stroker a blown 5.0 will give you about the same HP and torque numbers. But the 427 tends to be more linear. The blower tends to "come on", so to speak, at a certain point. A bit more dramatic.

the NA Coyote makes less power than the other two, by quite a lot. But it's extremely predictable and easy to drive.

Whichever motor you choose, install EFI right in the beginning. I'll never mess with a carb gain.
