ID my block? Just trying to gather as many specs as I can about this motor I purchased and was looking for some help.
Google hasn't really solidified my questioning.
Block Number: 12559378
Heads are 241
Intake: 12561184 (I understand this is the LS6 intake off an FBody)
I mainly curious about the year. Apparently there's enough of a different between the years to require separations for certain parts.
Thanks guys.
