Can anyone tell me what piston #L2169 is?
Thanks

Dan, that would be the TRW replacement 11:1 409 piston. They are the same as the factory piston ( exactly ).
Engine requires 4 of 2169 & 4 of 2170.:cheers

Thanks Aubrey.
I have all 8 pistons in a JA block.Unfortunately this motor ate 6 lobes off the cam and a lot of the metal went through the engine.
The pistons are 0.60 and if I need to replace them I do no THE GUY to call.
PS--I bought the motor that way.
