67 Barracuda Notch with 273

My buddy had a slant that could barely make it up a hill. Rear end was a 8 1/4 2.24! He put a 3.21 in it and could roast the tires in first. The 273 is a little soft on the bottom end. It needs a taller rear than most to get happy. I'd look for a 3.55 or better in a 7.25 rear. The 273 (small bore 318) loves to rev so a little R's on the road wont hurt it. Super nice car BTW, love the color!
