340 T/A Demon??

No it's definitely a T/A block I have...Not "-6"...it has the correct stamping with "ta" at the end of the part # on the block.

I haven't confirmed my car has this block - but I was told the TA motor I have is not a AAR/TA VIN per Barry Washington over at Hamtramck-Historical.
He basically said the vin on the motor is too late 1970 production to be one.
And said these leftovers made it into regular 340 cars...Just want to know if anyone has one or heard of one. I can't imagine there were many "leftover" blocks as some were probably warranty blocks for the TA cars.

Appears to be a real one off thing.
