I do think a stroked Coyote would be the best of both worlds. I would build one in a heart beat if I didn't think I would be a guinea pig for durability testing. N/A Coyote motors pull hard above 4000rpm and really sing between 5000-7500. Which for isn't what I want in a dual purpose car. Bigger cubes from a bigger stroke like in the 5.4 would really help with the torque. You to need to gear the Coyotes aggressively like DSE did on their test car, but then you lose some of the easy going highway street manners. The blower cars have a better power band, but when I drove one, the power came on so strong at about 3000rpm that it felt a little like an on off switch. I'm sure you could get around that with different cams, and slightly more aggressive gearing, but the point I'm trying to make is that right now is that the only smooth mod motor I've driven (4.6 3v, 5.0, 5.4) with a flat torque curve is the blown 5.4 and that is simply to big a motor to put in a little '65.
The problem I keep having in making a decision is whether I want the simplicity and flat torque curve of a 400 plus cube Windsor, or the technological benefits of a blown Coyote. Both would weigh about the same, with the Windsor being the better track motor, and the Coyote being the better street motor.

I forgot to include the link to the 351 info:

This one is at the top of my list so far. Just needs a trick EFI setup.
