Please help me identify this K-member

mr. sinister... i'm guessing that the k-frame i have is not going to work to put in my 69 m-code to hold a 440. do you happen to know if you can put a 440 on this frame with special motor mounts? if i can't use this part, i'll probably sell it. do you have an idea of what a 340 k-frame is worth? thanks again for your help.
Jim...Schumacher makes mounts that’ll mount your 440, but it won’t appear stock.
