340 TA

Were standard 340 blocks sometimes used to warranty T/A blocks?

YES. The cheapest way to get the car back out the door was the name of the game then, just as it is now.

The "-6" just means that the core in that block had been used 5 times prior to that one making your block #6.

Ok thanks that's interesting
