3.55, 3.73, and 4.10 Gear Info Needed: Highway RPM
 

what rpm are you running with either set of gears on the highway around 75mph?

i was looking for a gear set that i could use as a DD without destroying the pumps filling up all the time.

id also help to start what ratio your running and economy, if known.

thanks

Just my opinion with having 3.23, 3.73 and 4.10s in my 94 Z28. You will hate the 4.10s without a 6 speed transmission. It will launch like a beast but the RPMs on a highway cruise will get old real quick and if you care at all about MPG then best to skip the 4.10. In my opinion 3.73 gears are a great all around gear for good performance and livable gas mileage.

I just got my 3.73's in and I havent really got on them yet due to break in, but I can tell you that its a much improvement over the stock 3.31's.. as for RPMS I'll take a look tomorrow when I go out what I'm tacking at 75mph

3.73s - 2500 or 2700 RPM @ 70 MPH...can't remember which.

PM me with your e-mail addy and I'll send you the speed vs RPM spreadsheet.

are you refering to me? lol

Yes he is lol

You and whomever else wants it.

373s, 2200-2300 at 70 mph.
