Yeah I’ve been running an AX-15 behind a 5.9 magnum in my 72 Duster for the past 4 years and 15,*** miles (8,500 of those coming between September-January). It’s 99% a street car but I have run it down the strip a few times and autocrossed it some. I’m running 2.76’s with 25.6” tires. I had 3.23s in it originally, but that made first gear nearly useless unless on a hill.
