    running 3.73

    i run 3.73 in mine and i get a 22 hwy and 15 city. my computer says my average is usually between 19.5 and 20.8 but 90% of my driving is hwy. the 3.73 is a nice gear package to have when you wanna hand someone their arse.

    So it sounds like everyone is on board with the 3.73s ? I just added SFCs and some Nitto 555DRs and want some gears just didnt know weather to go with the 3.42s or the 3.73s...A4

    If you're gonna spend the money.. you might as well make a decent jump... the 342s will be better.. but not as fast as the 373s....

    I have been reading around but what do you guys think is the best set up to get, meaning no wine, longevity stuff like that, I was looking at the Richmond 3.73 gears, and should I get the instalation kit as well ?

    Thumbs up

    The LS1 power band starts @ 3K, and with 3.73's @ 80 MPH, you are sitting just out of it, with 3.23's you will experience a dead spot upon exeleration.

    I have 3.73's coupled to a Y3000 2.0 STR stall, the gears coupled to the stall will make an entirely different driving experience. I also replaced my POS stock flexplate with a TCI SF29 race grade unit. You will need longer bolts to attach the converter.

    If I had the stall to do over, I would have gone with a 3600.
