340 T/A engine compete

I have a real T/A which I purchased in 1975, unfortunately the guy swapped the motor for a standard 340, no T/A engine so I would love to buy this. But I’m a old married guy and don’t have that kind of cash. It would be interesting though if mr Ellison could let me know what he needs to check if this motor was from my car originally. I have tracked down and installed a T/A top end into mine, but have no info on how to trace such things. I do have factory build sheet. Good luck, note that I paid $1,050 cash for my car in 1975 as a present to myself for my 18th birthday.
Very simple. The six numbers of the motor are 305532, does that match the last six of your vin?
