Hi everyone new to the site I have a 1971 ford f100 stepside pickup. Has a 390 bored out to a 396 stroker c6 trans and 2.75 gears in the 9in rear end. 2nd owner my dad and I got it from the original owner had stock 302 c4 trans and 3.50 gears in the rear end with about 80,000 miles now with all new motor trans and rear end she sits there with 52,000 miles. We did all the swap when the odometer rolled over to 00,000. You can see the walk around of my truck at YouTube - the boss 71 F-100
