Dumb Question, LS1 vs LS2 Flywheel?

[SamHatco]

I'll probably be flamed for this one, but does anyone have pics of a LS1 flywheel and a LS2 flywheel? I want to make sure I have the correct flywheel before I purchase the LS7 clutch setup. I purchased a T-56 tranny with clutch/flywheel out of an 05 GTO has about 16,000 miles on the tranny. My understanding is that this tranny is called the M12 and is setup with a little bit deeper gear set. If I did indeed get the LS2 flywheel then all I need to purchase is the LS7 clutch and pressure plate.

Correct.. I dont see why you would have an LS1 flywheel.. The GTO didnt come with a LS1.
But sorry i dont have any pics

The LS1 flywheel is flat. The LS2 flywheel has 6 pedastals where the pressure plate bolts.

I have an 05 GTO T56 as well (checked the p/n to be sure). But based on Andrew's description of the flywheel I have an LS1 flywheel. I can still use it if I want to right?

Here are the part numbers I found on my stuff - anybody decipher them?

Flywheel - 1266 4130 N
Pressure plate - 21205-4L10B
Disc - 12570808 4L30B 1829 annd 83301

Thanks. -Bob

the ls7 clutch should come as a kit with the flywheel. I'd recommend buying the kit with flywheel. Most of the shop manuals tell you to replace everything at once, because it is a matched set. I'm also pretty sure the LS1 flywheel will not worl with LS7 clutch.

According to these pics and source (LS1GTO Knowledge database) the Vette LS2/LS7 flywheel has the 6 pedastals but the GTO LS2 does not.
