is this guys post right?

I run 4.10s with my 93 T-56. But one question. What are your stock gears, did you have the 3.23s or the 2.73s because that would matter what tranny is in your car. If you have the 3.23 gears originally it should mean that you have the
1st -2.97, 2nd -2.07,3rd -1.43, 4th -1.0, 5th - 0.8 6th -0.62 gearing in your transmission.
and the 94+ has
1st-2.6,2nd-1.78, 3rd-1.3, 4th-1.0, 5th-0.74, 6th-0.5

If you have the 2.73 gears originally your gears would be even deeper.

So like fastbird said 3.73s are actually deeper than 4.10s in a 94+ in the first 2 gears. 4.10s in the 93 are more like a 4.60 gear in the 94+. Like I mentioned earlier that I run 4.10s but it is really deep. If you want to drag race alot then they might work for you but for the street 3.73 are probably a better choice. I like to overdo everything so that's why I have 4.10s. But I must mention that I have to run a 28" tire (275/60/15) tire for drag racing or my 107-109 trap speed is too much for 4th gear and I'm forced to shift to 5th.

Depending on your milage you put on your car, you can run drag radials all the time. I would recommend the Nittos for longer wear vs. the BFGs. Just becareful if you drive the highways with worn drag radials in the rain. It could get scary."

Yes, the 93's had higher numerical 1st gear ratios on the T56's. Overall gear ratio in 1st gear is the 1st gear ratio X the rear axle ratio:

93's:

M28 3.36 1st gear: 3.36 X 3.73 = 12.53
M29 2.97 1st gear: 2.97 X 3.73 = 11.08

M28 3.36 1st gear: 3.36 X 4.10 = 13.78
M29 2.97 1st gear: 2.97 X 4.10 = 12.12

94 and newer:

MN6 2.66 1st gear: 2.66 X 4.10 = 10.91

 

dag thats crazy..... Is there a way to tell what gear came stock in the m6 in 93? when i got my car it had the 4.10 in it.

Look in the glove box for codes.

GU2=2.73
GU5=3.23

The M28 came with 2.73, M29 with 3.23
