You won't need to mod these motors, much, to see a realistic improvement in a Foxbody. They're making 412hp @ crank, about 374hp @ rear wheels. This is a good bit stronger, HP wise, than MOST of the "typical" HCI push-rod 302's running around.

I would love to do this swap in any old Ford-related vehicle. Finding one in an affordable price-point is the hardest part (for starters), then the next debacle would be getting it wired & all bugs ironed out at an affordable cost too.
