Everyone, The Longblock above that I show VIN stamping on was assembled T0912CKO.......BUT here's the deal on the VIN stamp.....What I report as a W really doesnt show.....The LETTER(??) didnt strike the block as the NUMBERS did.
After writing Mark Meekins I received back a letter on Jan 28, 1998. In part he wrote.........

" Without a letter code in the VIN there is NO way to tell what the original application was. The one problem usually encountered when the VIN is struck on the bellhousing boss is the loss of characters or what appears as partial digets.
....................
The proximity of month closest to the assembly date of the engine, T0912CKO could make this a Nova engine( Sept VIN)or a Chevelle engine(November and Decemeber VINs). Of course, it could have also been used in January built Chevelles, but these are slim as the LS6 was geared up for production in mid to late Decemeber(actual date is unknown).
The Chevelle VIN for March is out of the question. I know this doesnt clear up your mystery, but I hope it gives you some insights.

Sincerely, Mark Meekins "

His letter gives other info about what months that VIN could have been used on Chevelle and he says that only month it could have been in a Nova was Sept 1969.....

If you guys know better about my eng I APOLOGIZE for misstating the truth. If it matters I can scan and display entire Meekins letter
