F8L GT Posted May 29, 2013 Report Share Posted May 29, 2013 can you replace just the 6th gears in T56?Yes, but you have to change 5th and 6th together Link to comment Share on other sites More sharing options...
F8L GT Posted May 29, 2013 Report Share Posted May 29, 2013 (edited) I was unaware machs came with any gears other then 3.55's.I was just saying the machs come with 3.55s that's why they had the.62 5th ratio Edited May 29, 2013 by F8L GT Link to comment Share on other sites More sharing options...
copmagnet Posted May 29, 2013 Report Share Posted May 29, 2013 6th ratio is 5th gear correct? I read that and was like wait, machs dont have 6 gears, lol Link to comment Share on other sites More sharing options...

01yellercobra Posted May 30, 2013 Report Share Posted May 30, 2013 The machs that came with 3.55s had a different 5th gear to make cruising rpms the same as a gt with 3.27sLike I said, I'm pretty sure it was across the board. I had a 3650 in my Cobra and my buddy had a 3650 in his 03 GT. His cruise rpm was lower than mine with the same rear gears. The math added up to him having the .62 gear.

GearGambler Posted August 1, 2013 Report Share Posted August 1, 2013 I have 3.31 gears in my 94 - take offs from an 08. i get between 18 and 26 MPG depending on how I drive the car. 75 mph is a perfect 2200 RPM on the highway.

Moderators Psychorugby Posted December 9, 2013 Moderators Report Share Posted December 9, 2013 Not sure why, but I'm starting to second guess my choice in gears. I bought 4.10s to pair up with my T-56 (the original T-56 from back when only the Viper, Vette, 00R had them). Is this too much gear? Keep in mind that I plan to have a 600+ hp/lb-ft 408w in front of it. Link to comment Share on other sites More sharing options...

Based on calculators I've found online, I think I might be okay.For that you just have to make sure your tires and suspension are up to it. I run 3.90s with drag radials and I'm about where you are power wise. First spins a little when the tires are cold. Second usually hooks. I have the 03 T-56 though.

Orange 94 Posted December 10, 2013 Report Share Posted December 10, 2013 373 with 8.8 swap. Not much of a first gear with the blower. Usually give up on trying and just use second for launches. Link to comment Share on other sites More sharing options...
1997cobra Posted December 16, 2013 Report Share Posted December 16, 2013 430s are nothing at 80mph for a mod motor.
