3.73's or 4.10's
 

hey, im going to be getting gears today but i dont know what ones to get im building my car fort street/strip and i dont know what gears to get 3.73 or 4.10 and also i wanted to know where i can get a speedo gear so my speedo will be right with the new gears. let me know what your input is thanks.

neither. Go with 3.90s. A jump from 3.42's to 3.73s just isn't worth it, and 4.10s are great, but if you do a lot of hwy travelling your mpg will hurt. 3.90s give you a nice jump in acceleration while still retaining some kind of good hwy mpg.

i have 4:10s in my car and with the manual 6 i get 21mpg highway and at about 80mph im at about 2100rpms so its not crazy loud with exhaust. my vote is for the 4:10's

well the reason im looking at 3.73s or 4.10s is because im getting a deal on the gears either ones for $90 ( yes there new )

with a m6 youll be fine with 4.10's if you were auto i would stay with 3.73's

you could recalibrate your computer with a little hand held tuner. tranny shops could have the speedo gear. i would do 4.10's out of the two.

:werd:

But I believe with the LT1's powerband, 3.90's would be a better choice. But, since your getting a deal, go with the 4.10's.

okay, i think im going to go with the 4.10 gears, and how do you change the speedo with the hand held tuner ? and how much is it to do ?

the hypertech is answering yes and no questions and entering gear size and rear tire diameter. double check off of a buddies car or gps though.

alright cool, how much is the hypertech tuner ?

alright thanks, i think thats a little to much for me right now since i just ordered alot of parts, but does anyone know how much the speedo gear for the trans will be and where i can get it ?

:huh:

dont need a new gear, need to reprogram the PCM to calulate the pulses

you can do that or you can change the speedo gear to make up for the gears

eh i've never had luck with speedo gears. i would inquire at a local trans shop though. they are cheap and you might find someone with more experience.

I thought the speedo change was only for 93s?

And look on ebay, a lot of people dump the hypercraps on there.

you think correctly, you cant "change a gear" on 94+ cars, they need to be tuned

really? ah my bad. thinkin about it mine is electronic and not mechanical. ebay! or a mail order tune?

Yea, you could prob benefit from a "real" tune vs. the hypertech thing.

im gunna be the guy who says 3.73...everytime i look on my wall i say no more 4.10...i have my litterally bald ring gear and my sheared in half pinion mounted on my wall with a plaque that says this is why i dont race corvettes...but anyway the 4.10 in a 10 bolt is too fragile...if you plan on putting some power to the ground later on get the 3.73 for now and save up for a 12 bolt

get 4.56s for a 10bolt. and use a gps for your speedometer
