340 T/A Demon??

Sorry for the confusion on this one....

I have a 1971 Demon 340 with it's # matching 340 motor in the car.
The casting on that is 11.69....I don't know what part casting this motor is, yet as I can't see it with the motor in & headers on.

Then I have a seperate stand alone 340 T/A Block on an engine stand....that date casting is also 11.69 - it's a real T/A Block with the front pad having the "SP" on there as well & was out of a non-AAR/TA car per the vin #...I will consider selling that block. It has a crank/oil pan/windage tray, too..I'll try to get a pic or two up here of that motor.

My question was really just around if anyone knew of any 340 cars that came from factory with the leftover T/A blocks?
