<<Old Boss and Shelby Cobra Mustangs beat Corvettes and Camaros any day.>>
They don't beat old Corvettes and Camaros, even back in the day. Heck, they won't even beat new Vettes and Camaros. Even the Boss 429 Mustang was a dog. Loads of potential, but it wouldn't run at all. The new Mustang Cobras would beat it.
FE motors, while great for nostalgia, are good for nothing but boat anchors. They won't hold up if modified, and you can't make that much power out of them anyway.(I'm talking big horsepower, like well over 600) The Lima 429/460 engines (basically copied from the big block Chevy, along with the 351 Cleveland...and yes, Ford admits to it), are far superior to the old FE's.
