Hold onto your mullets, folks, because the 1978 Pontiac Trans Am is making a roaring comeback! This beast rolls in with a brand-new cross-hatch grill, giving it a snazzier smile than the Cheshire Cat. Under the hood, the Firebird Formula LT Sport Edition flexes with a high-compression 305 cid engine at 155 hp, while the 400 cid engine, now rocking the 6x-4 heads, cranks up to a muscular 220 hp. Big thanks to Gateway Classic Cars for the drool-worthy images!
