Thread: Rear End question

Tweet

Seems you should have asked those questions before you bought it. The 4/10 will probably cut your milage by at least a third.

Thing is, i knew they were cheap, and that it was a posi and that it would fit my car, so i said, why not. Even if i don't use them, i could probably sell them for 600. Its a brand new auburn!! I have never had new gears on my car, so that's why i'm asking all these questions. I don't know what experiences i'll run into. Is there a chance that it would go past 120 on the highway, because i have a buddy that runs a 3.55 posi, on a 93 dodge dakota with a 5.2 and no major mods, and goes past 180km/h no problem.

you say you have the 700r4, so it want be all that bad with the overdrive. my truck 700r4,4:10 gear@60 mph tunes about 2600 rpm's. i get 20 mpg. hard to have a lot of power and gas mileage. low gears and hi speed dont mix, unless you have a good motor.

You mean, how soon i'm planing on overhauling it or cracking the block? I want to have a lot of fun, even though the car weighs 2.8 tons, it hauls its own weight pretty good. It's the original 305, with 327000kms on it, never been overhauled. Lifters tick, a/c clutch squeals like a bitch, and it's not the nicest caprice out there, but it makes me happy. I plan to getting the body work done by september.

That S10 of yours has the LT1 tho. It probably would work at higher rpm's anyway. As for the 700r4, i was thinking the same thing, but my block originally had 180hp, and i pumped it to about 250, with the air intake, exhaust, fuel pump, and a few other things. I'm planning on dropping a hot cam in it, but, i don't know how well that's going to work with my computer.
