How my car feels after the 3.73/posi/disc swap!
Wow, glad to see TG.O back up! Some of you know, but some of you don't- I did my 3.73/posi/disc swap two weeks ago!
I had trouble with the brakes (bad master cylinder) that took me a week to work on, but everything's working fine now.
The car feels GREAT! Wow! When I punch the gas at a stop, the car really pins me in the seat. It roars to life much faster, and as a bonus, my 1-2 shift got harder! Flooring it on a highway gives me the same ear-to-ear-grinning results.
As to the posi? Well, I haven't had much opportunity to try a burnout. On the one chance I had, I heard the left (cool!) rear tire start to spin, but my BRAKE warning light came on. I saw that and let off the gas right away- I must still have air somewhere in my brake system.
I built a homemade pressure-bleeder for my brake system when I did the swap; at the time, I used it directly on the brake lines. Maybe this weekend I'll adapt it to work directly on the master cylinder instead.
I want to get to the track soon!
Any questions? Fire away!

Thats good TomP, sounds like it went the way u wanted, but I have a different question for u. A while ago u posted something on your insurance and how low it is. I'm paying like $445 quarterly and I think thats way too much. How much are u paying again and what company do u have??

Reminds me of when I had my v6 Camaro. With the 3.73 Z28HO rear on it I could out run LG4s all the time. Sure do miss that rear...however I don't miss the poor mileage I got from it.

Glad to hear the swap went well!!
What happened to the speedo though?? That still working ok??
As for the insurance question, I guess $445 a quarter for a V8 isn't horrible, depending on your driving record. I pay $1,150 a year for a V6 with no points added, after 4 good years of driving. Hope this helps a little.

Thanks guys!
Crazeinc, that's the only way to spend a holiday, right? Cool to hear I wasn't the only one! The axle swap itself took me a day and a half, the brakes took a week
GetBlown, I've already noticed the drop in mileage. However, with my tall tires (P275/60r15's), my "effective" rear gear ratio with the 3.42 gear was a 3.18. Now, with this 3.73 gear, my effective's a 3.46- so my car's close to "stock" again. If I got shorter tires- woah!
JasonE, my speedo is pretty much back to normal (see my paragraph above). It's actually reading a bit "fast".. it used to say 50 when I did 55... now it says 50 and I'm probably doing 49.
My insurance was $3000/year, with accidents. Now that I'm an old man at 24, I'm paying $800 a year.
Oh and as to the difference between Jason E's insurance and Get Blown's old insurance- it matters alot what state you're in...

Hey Graeme's, thanks for fixing my stupidity!!
Tom brings up a real good point...I live in Massachusetts, which supposedly has high insurance rates compared to other states. What's funny is I pay the EXACT same rate ($1,150/yr) with full coverage that my parents paid when it was new!!
If I didn't want collision and cut some of my liability down, I could ensure it for under $700 a year. But with the school I go to (UMass Amherst) and the traffic I deal with, it just isn't worth chancing a hit-and-run with the body of my car being so good.

Oh hey you guys were asking about collision, too?
I don't have collision... I just have liability. I'm insured against lawsuits, my car isn't insured against damage. I figured they'd look at my '86 with (now) 205,000 miles on it, and say "It's junk, here's $500, and go away please." At which point I'd flip out, they'd call the cops, I'd get arrested, etc etc- it's not worth it. j/k
