The LS1 Fbody and GTO T56s differ only in:
- Gearset: MN12 (GTO) with 2.97:1 first vs MM6 (fbody) with 2.66:1 first
- Synchro design: triple/double cone (GTO?) vs double/single (fbody)
- Starter/bellhousing size/area: Can swap starters or clearance bellhousing
- Shifter and shifter-offset lever: can swap between the 2 easily

Everything else externally is the same.

The aftermarket GM T56 is a different animal, meant as an upgrade for the T5 3rdgen Fbody's to a T56 using the same clutch/bellhousing/shifter. You don't want to deal with an AM version unless you have a pre-92 manual transmission vehicle, and even then it may not be the best choice.

what do u mean the AM version

and how can u tell the difference between the camaro t56 and the gto? is there a different serial number on the housing ? any thing else ?

also i heard u can change the cup to fit a fbody shifter so the shifter sits more foware towards the bellhousing..but changing the cup, do u change just the shirter or the tail shaft, or?

i have 3.73 in the rear and the mn12 3-4 gear suppost to be a big jump, will it bogg my motor(ls3) or with the 3.73 be fine
