I had the 2.73 stock gears and went with a 3.73....yeah enormous difference. The only difference between the 3.55 and 3.73 is on the street. The 3.73 is a better street gear and a 3.55 is a better strip gear...racing of course. I was planning a a s/c as well, kenne bell, and I was going to probably have to change down. I would go with a 3.55 if you are going to s/c it, if you can drive it to its potential then you can easily look like it has a 3.73, driving is going to be the key factor here.

supercharged i would go 3.55 if not them 3.73s i think im going to regret not going with 3.55 when i get charged but all well its going to be fun anyways

3.55's supercharged is not a bad idea.

Go with 373's man .... Alot of people have build supercharged engines with 373's and a few with 4.10's .. I highly doubt that you will even feel a difference from 327's or 355's .....

good thing he's not going from 3.27s

Even if he was going from 3.27's to 3.55's he would still feel the difference. Its a supercharged car; you do not need to run that steep of a gear. You can if you want but I think 3.55's would be more suitable for your application.

So your all saying 355s with a supercharger, but I want 373s for the whole YEAR that I dont have the supercharger, sound like a good idea? or should I jsut stick with 355s?

Gears are expensive as well as labor to install them.. If you have money to waste, go for it, otherwise, just get the 3.55's, you'll be happy with them..

373...373...373...i lovem in my s/c stang, my 90' vert should be about the same weight as yours, go with 373, just be ready to shift out of first fast when racing
