11 inch flywheel

[SS454]

I did a search but did not find out for sure. Is this flywheel for a 396/427 or 454. 3973456n the date code is G15 and looks like a 2 after that http://www.yenko.net/ubbthreads/images/graemlins/dunno.gif.

Thanks

I have that casting number flywheel on my 68 Camaro 396 so it's for 396/427.
