Two Lane Blacktop has James Taylor (Fire and Rain, Sweet Baby James) and Dennis Wilson (Beach Boys) in a primer-gray 55 Chevy racing across the US with Warren Oates in a GTO. I don't remember the football field scene, though.

Bullitt has Steve McQueen in a hopped up Mustang being chased by a black Charger that hits a gas station and blows. I don't remember the Mustang burning down.

It's been years since I've seen either movie.
