i know this has been posted like 10 million times, but if you have 3.73's what rpm would you be at on the interstate going 65 and 75? because i thought i was stock but i drove on the interstate for the first time since rebuild and it seems to me like gears are pretty short and rpms are quite high on the interstate. i never really payed any attention until lately because everyone has been talkin about gears

You can jack the rear end of the car up and mark the tire and the drive shaft and count how many times the driveshaft turns to 1 rotation of the tires

if you thnk its stock look at the door tag under ax... itll have a letter... let me know what it is, itll tell ya what gears came stock.... its very possible that you have stock 3.08s... which i have, and 2500=85mph.
