Chris Ryan's 1978 Pontiac Trans Am

Chris Ryan's '78 Firebird is a loving tribute to that famous Trans Am from _Smokey & the Bandit_, but with style and performance that would have been nearly impossible when the Bandit was busy with Sheriff Justice.

It's not every day that you see a wild, IMSA inspired, 550 horsepower Vega. Byron Burnham went way outside the box with this one, and we love it.
