GM flywheel casting numbers

Hello All

I have a few flywheels I would like to know what they originally came
on. I can't find the info I need on the net and don't have books that
cover them. Does anyone have any info for me?
I tried to decipher the numbers as best as possible, but some were rusty
and hard to read... They are as follows

L284 3714463
K292 3973456N
H275 3729004

Thanks for any help....
