I have no knowledge, of any later built 1970 LS6 than 7/20/1970.
T0108CRR . . . .Hmmm! January 8, 1970 engine assembly date and an August 31, 1970 casting date.For that much money, I'd rather have a more believeable LS6 casting date, than the, August 31, 1970,
"engine block casting date", [H 31 70].......
I would be concerned, that this engine never left the factory, in a "FACTORY BUILT LS6 Chevelle SS"..
Mainly because of the blocks "late casting date", but also because the [CRR] "block appears to have been re-stamped" I would have, some really, really serious doubts, about it's ORIGINAL authenticity..............Don.
