Can't make up my mind on which to get, leaning towards the 3.73's but I have somebody giving me a good deal on some 3.55's, what are the pros and cons on these size gears?
Any and all replies are highly appreciated, thanks.
Oh, car is a '91 Notch 5spd if it matters.

I have 3.55 on all my stangs, one is supercharged, one NA, one carbed, all 347 strokers. It's a good, mild street gear great for freeway driving and commuting, with decent gas mileage.
However, my cars feel somewhat sluggish with that gear. You would get more of the feel of acceleration from 3.73 or taller. I was like you, I got the 3.55 gears because they were cheap and plentiful. But doing it again, I would go 3.73.
3.55 isn't horrible though, you can live with it if you're on a budget. But you'll be happier with 3.73.

I have 3.73s in my 01GT.
Go with the 3.73s you will be happy with the acceleration and freeway driven.

I would go with the 3.73's. It would be perfect for your 5.0

I have 3:55s, it is good for me because I drive on the freeway alot. But as far as the track goes I wish i had 3:90's or 4:10s. 3:90s seems like a good, more aggressive ratio. Not a extreme as 4:10s. You never hear about many people using it either...

Go 3.73's NA, 3.55's if it's charged. 4.10's in a DD Fox or SN are a waste in my opinion.
3.90's were a marketing gimmick...and it worked. Less than 5% of the cars out there can even benefit from it.
