Hello. I just bought a ‘79 Malibu wagon project. A previous owner swapped in a 305 TPI & T5 manual trans from a ‘91 Trans Am. They also swapped in an ‘87 GN rear axle with 3.42 posi. It also came with 16” Camaro wheels shod with 245/50R16 (25.6” dia) tires. The gearing feels really tall! I’m debating running a 255/60R15 (27” dia) tire, but it’s going to make the gearing even taller yet! Would it be THAT noticeable? I’m also debating going 3.73s or 4.10s. It’s a daily driver - mixed hwy/city - 35 miles/day. I’m fine with 17+ hwy mpg. It gets 20+ now (running rich). Any input would be appreciated. Thanks!
