Can anyone help me find a gm part number? It's from a 168 tooth flywheel. These are the numbers on it:

1255 4130N
GM3B
136E

I put it in google but just found very basic information. I need to know what it's compatible with engine wise.

 

from what i could gather its for a 55 to 85 chevy and is used for the 11 in clutch.

 

Really? Where'd you find that? This is supposed to be from a stock setup from an 02 LS1/T56 combo.

 

googled chevy 168 tooth flywheel and looked over the stuff real quick. could be that its something i missed.
