swp to a 6 speed and u wont have a mpg problem. ..
with a centri you can easily stay out of boost for normal driving.. i dont see your mpg argument personally.. i have 4.10s and get good gm.
as far as traction goes, i would step up to a 3.55. 3.73 are not really that big of a change.

I wouldn't go back for mileage, but for 1/4 purposes I am actually thinking of going 3.73s from 4.10s. I don't want to run a 28" tire and I also don't want to top out 4th in the quarter once I start spraying and once my new blower is on.
Gas mileage is only gonna go up by a couple if that, but I'm not even sure about that if you are running bigger cams. If you have aftermarket cams, you know what I'm talking about. There is that rpm that they start to really smooth out....I would hate it if my car cruised under 2k on the freeway with these cams.

i recommend a taller tire first to see if that helps you out. Going from 4.10s to 3.73s is not going to help out your gas mileage. Personally, the thing I don't like about my 4.10s with my setup is 1st and 4th gear is way to short. 3.73s will help you out to about 120 mph rather than 110 with 4.10s. 4.10s and centri pulls like nobodys business though.
You could always keep 4.10s and go with 6 speed tranny. If I change my gears I will opt for 3.55s and a taller tire if I build my rearend some day. I will be going to a taller tire first though.

ugh this is the decision that had been plaguing me as well. I am about to install my vortech and can't decide on 4.10 or 3.73. I also have cams too. I don't want to be hitting the trap just as I shift to fourth or something. But at the same time I won't be going to the track alot. I also don't want to have to run dr's just to be able to get on it in the streets. Don't want to be all over the damn place when I hit boost in 1st and 2nd. I may go with 3.73 even tho I loved my 4.10's on my last stang that was n/a. I picked up mpg in the city and lost some on the hwy on my non pi 96.
