My chevelle book does not go into great detail on Numbers .
What i have is Vin: 1363701521352
The motor Number : TI1IICTW 101521352
The transmission left side over the pan reads :
01124992
and the right side tag reads 293 above 70-CA-269.
Now the Canadian Documentaion reads T1111CTW (not on the Motor) just the option list .
I have no build sheet so i can't check it for information .
Could the plant have used the (I's) for numbers?
Thanks for your time in this matter Joe
P.S Yes i checked the numbers over and over

those are #'s not letters T=tonawanda,should be #'s stateing the month and the day it was assembled.my canadian 70 reads T1201ctx, tonawanda december 1 ctx is 396/402w/manual trans. ctw is an auto trans

sounds like a #'s matching motor to me the last 6 digits match your vin#

Could the plant have used the (I's) for numbers?
On engine date codes an I was used in place of a 1. To a lot of workers, they could not tell the difference in the 2. So yes, its very common especially when there is more than one 1 in the date, like in you case.

Hi, Looks like numbers matching engine but not trans,but 70 model year trans pretty close to original Ray

Ray , thanks for your help ,, thats what i was afaid of the trans not matching .
