Can anyone tell me the what kind of flywheel this is?
Casting #'s on the back 3873456N GM2 B171
thanks for the help ;)

Those numbers sounded familiar so I went and checked.I have the same flywheel,fits a big block
68 tooth 11 inch clutch.It won,t fit a 454 as it doesn,t have the extra weight. graemlins/thumbsup.gif B171... I think that date code is Feb 1,1971.But thats just a guess.

thanks for the reply! smile.gif
I will be getting it ready now for my TKO install now that I know it's the correct one for my 350 small block.

Hopefully you will take lots of pictures of your TKO installation. Maybe even a pattern of your tunnel cut, and tunnel repair.. I am thinking of a TKO for my 66 convertible...

Yes, i'm interested very much in the tko 600 but waiting to see how the install with Jeff out in California goes in July.
