Hi, i've got a 87 camaro V6 2.8l and I know its not really fast, so i was wondering about changing my rear-end gears for like 3.73 or 4.10. Is that a good idea? i know i'll loose some top speed but anyway. Is it hard to do? In what vehicles could i get the new gears at a scrap yard or should i buy em new??? And about a shift-kit for my th-700. Will I see a difference. Is it worth the 140$ ? thanks
Changing gears in the rear end is a good idea but I would not recommend doing it yourself. It is a very exact process and you need several differant specialty tools. What you actually looking for is called a V8. That should provide you with all your answers. But really, changing the rear gear to 3.73's will give you a noticable differance. 4.10s are a little much for the street but will work. We have a set of 4.10's in a '59 Chevy Pick-up that has a 402BB. It runs fine on the street but my father just putts around in it.
