Engine ID

Happy Easter to all,
I have a big block Chevy engine I am trying to ID. The numbers on the block are
T0106TRK. I know what they all mean except for the RK. I believe they designate the transmission & engine.
Can anyone clue me in on their meaning?
Thanks,
Bill

Re: Engine ID

Thanks for bounce back I now know it’s a 456. None of the last to letters reflect anything about the transmission, correct???
