Difference in Gas Mileage Between 3.73 and 4.10's

3.27 vs 3.73 vs 4.10 (took a couple hrs 2 complete... enjoy)

03SuperchargedGT · February 24th, 2009, 06:28 PM

im running 3:73s on my car and love them, 4:10's may be to much for a supercharger

BakerFX4 · February 24th, 2009, 08:04 PM

+1 for 373's on a blown car.

B0B · February 24th, 2009, 08:10 PM

i'd say go with the 3.55's if you can get them for a good deal. unless you have big aspirations for the car, the 3.73's will suit you. otherwise you will run out of gear faster than you think.

I am doing 4:10 with my auto and a roots blower. but either 3:55 or 3:73s wouldn't be bad. go on youtube and see what some poeple do with that amont of power and streetfire.net to list a few

Renegaderacer · February 24th, 2009, 09:42 PM

thanks for the feed back and still with the short throw is abit of tranny noise shifting normal?

AggieStang · February 24th, 2009, 09:52 PM

373s no question about it.

yojoe600 · February 24th, 2009, 10:14 PM

3.55 or 3.73 bc 4.10 lose too much gear

Renegaderacer · February 26th, 2009, 02:31 PM

right yeah once again as said before i mean it loves the 3.27 up top but down low the car behaves like it wants a gear so ill get 3.55 if cheaper 3.73 if close!

Renegaderacer · March 3rd, 2009, 04:46 PM

on a 3.73 how hard do they still pull up top?

bottlefedbullitt01 · March 3rd, 2009, 05:23 PM

i got the 410s and still love em! Although if I were to add any more power i think Id change to 373s. my car roasts 275 drag radials all day long at 15psi...just up to you bro
