are there a difference from 90-93 ls trannies and the 94+ ls trannies?? i just test drove a 92, and the gears seem shorter than the 94+ but i'm not sure, i've only test driven a 94+ teg as well. thanks guys.

the blocks however are the same correct?

 

I have read in another forum where the gearing is slightly different between the 90-91 and the 92-93, no proof though. The 94 trannys are when they went to a hydraulic clutch. Gearing could be different as well.
