I think there is an article at www.Zdriver.com about installing t56.Also there one more choice-Termec 5 spd gears are: I 3.27 ,II 1.98, III 1.34, IV 1.0, V 0.68.If you are interresting check with Forte's Part connection 781/647 1530.I think they have web site too,soory don't know address.Termec could be bolt to LT1,not sure about LS1.This tranny holds up to 500HP and over 400 tourque.Price,not cheap,around $1600....hope this helps.
