Dropped the vert off at VA Speed during my lunch break to have the Gentleman Cruiser's old 3.90s installed.... will report when I get the car back tomorrow evening or Thursday. Wasn't going to do anymore mods, but Kevin made me an offer I'd have been stupid to pass on :D

Enjoy! 3.90's are the way these cars should have come from the factory so you're right, this isn't a mod - it's a factory correction. :D

BTW: There are more than a few people driving around with parts off the Cruiser. :yesnod:

I am not to smart on gearing, what benefits do you expect, other than faster launches, What is it going to do to rpm @ cruising speed

It will have the same effecive gearing as a C5 Z06 with the MN12 trans wich is steeper gearing. The car will accelerate quicker and still only turn 17xx rpms at 75mph cruising.

That is a great mod for a stock like HP Vettehttp://i29.photobucket.com/albums/c293/elsloan22/emotions/thist2_761170_beer_butt_beach_babes.jpg

You're going to love the gears Brian.

They really are going to wake the car up. They are also going to be awesome out at ACU-4. I know when I had the stock 3.42s 2nd was to tall, and 1st was to short. With the gears it will be just about perfect for you.

67? You're supposed to play the back nine for it to count :lolsmile:

Just got home from picking up the car from Va Speed... so far it seems great. I put some cardboard down under the rear of the car to check for leaks etc., but I'm not expecting any.

The service from Va Speed was great.... the woman working the front desk (Mario's wife, sorry I can't remember her name) was extremely professional on the phone and when going over the car on drop-off inspection... and she called me back in a timely manner which is huge to me.

Then George was great with too.... he called me this afternoon to inform me the car was ready right on time and had a copy of my invoice waiting for me. The stock diff was bagged and boxed in the trunk of my car. Pretty nice for a performance shop to professionally set expectations and then meet them properly.... IMO this is rare in the auto industry... especially the performance aftermarket industry; it was nice for a change.

As for the car.... it's great.... this is why people thik C5 Z06s are "so fast"... it's all the gearing. Now I'm sure in a 3rd and 4th gear pull my 430 rwhp Z06 would pull a few cars on me, but 1st - 3rd any differences are un-noticable. My stock 275s are useless in 1st gear... 2nd and 3rd feel great... 3rd gear from a 60 roll is just perfect.

I did a few figure 8s in a parking lot and the limited slip is 100% quiet, no chatter. The only "negative" I can pickup on is that there is a sight increase in differential noise when under load.... I.e. cruising at 50+ and slowly accelerating you can hear some gear noise vs. the stock gears, but this was 100% expected. Every review I've read online says that the higher ratio gears (numerically) increase gear noise.... I experienced the same thing when putting 3.73s in my Cobra years back.

Overall I'm extremely happy :) I'm done for now until I find some headers for a deal I can't pass on....

You mean you have to play ALL the holes? Dam! :cuss:
Sounds like the rear change went smooth. Now, go Mustang hunting. :thumbs:
