I talked to a local guy who is selling a 4.11 non-posi drum brake rear end in great shape out of an 87 iroc for $250. Right now I'm running the stock rear in my 1983 Z28. It would be a big jump for me, haha!

I don't race this thing, but I only drive it here and there for fun. I have a company car for a daily driver. Is 4.11 too extreme? For those of you that use a 4.11, what do you think of it?

and if I don't do the swap myself, is the labor going to cost me an arm and a leg?

I wouldnt get a new rear if it wasnt posi. But thats just me. 4.11 is a tad bit overkill for daily street driving, on the highway your going to be way up there in your RPMs. Then again you dont daily the car and only drive it for fun. If you drag race the car i would go for something like 3.73 or 4.11. How much power are you making?

the car isn't a powerhouse, maybe 200-220hp or so. i might take it to the strip on street tires once or twice for fun. i'm just interested in improving my 0-60 time really.

a posi rear end of any type would help. Getting power to both wheels off the line is better than getting power to only one wheel. 250$ is kinda expensive for a non posi rear also. What kind of brakes does it have? I have 3.42's in my car and its a good balance, although my car is my only car. Most people who have strip only cars use 3.73 or 4.11. If i was you i would get a posi rear end, somewhere in the 3.42 and up range. It sounds like 4.11 would be a little overkill for what you want to do with your car, based off the i drive it every now and then and plan on taking it to the track a few times assumption im under.

QuickStyle

if you are running the 700r4 like your info says, it has a 3.06 first gear, that combined with 4.11 rear end, you will have major traction issues.
