14015445 is commonly used in light/medium duty truck engines. To my knowledge, they are the last breed of MkIV, thus they have the least amount of metal in them, I think they are good enough for up to .060 over bore, but cannot handle .100+.

f 25 2 date code for June 25th, 2 is year so based on above would be 82.
T0722XCH enigne code, T=Towandowa (sp) engine plant, 0722 is assembly date (July 22nd which is in line with the June 25 casting date), and XCH is useage code and I could not find any listing for a big block with the XCH code.
