Can anyone tell me or point me in the correct direction of the gear ratios for the t-56. I am doing some comparative graphing and need the numbers to complete my functions. Thanx guys

You do realize that there are several T56 ratio sets, right? The LS1 Fcar application is:
2.66
1.78
1.3
1.0
.74
.50
2.9
The GTO, CTS-V and Z06 share a different set. There was a 1st year only Fcar set as well.
The 03-04 Cobra has a "blend " of the two mainstream sets.

i thought all the lt1 were the same and in 98 is when they went to the 2.66 ones. i could be mistaken i guess though. though i know that there was an option for the lower gears in 92 or 93

The 3.36 set was a one year option. The 2.66 set was offered with an LT1.
