Are these L48's correct?

[Boston14]

I am new to this group and would like a little information from you guys that are so knowledgable.  My friend and I have very similar 1969 SS Camaros. Except one is a Conv. and one is a Coupe. One has a Tonawanda engine coded T1120HB and the other has a Flint engine coded V1113HB. One is a 386 block dated K 8 8, and the other is a 388 block dated K 12 8. VI numbers date the cars to the First week in Dec. 1968, and the last week in Nov. 1968.  Could this be correct? Or is something wrong here?  Any help would be appreciated. Thank you.

Nothing unusual. Flint and Tonawanda both built L48s.
