Need help to identify straight six

[3drburb]

Hello engine guru's, I am looking for help with two 6 cylinder motors.

Both has the same casting number 3921968.

Here is the numbers off the pad by the distributor.

One has ID# F0602TCK. I am thinking 67 plus Chevy truck 250.

The other ID# F0923BB and below that is 19W318135. This one is hooked up to a powerglide, I don't know if that helps.


Any help would be greatly appreciated.
Thanks.
