Looking for the '69 COPO Camaro 4Spd. this L72 belongs in?!?!

[Maxibrake]

Hello guys, I'm new here and thought I'd throw this out there and hopefully, find the car this engine belongs in.. Pretty sure it's a '69 COPO L72 427/425?? It runs, big, solid flat tappet cam. Heads are the CORRECT "291" Square castings but the date is too late (J-30-9) I haven't disassembled yet.. Came out of a '67 Caprice I recently purchased. Pulled it to put a tamer 454 in and checked numbers and researched how rare this engine(Or at least the block) is... Hoping the car is still around?? Trying for some good photos tomorrow.. NUMBERS BELOW��

*Block #3963512
*Block casting date is C-11-9
*Right Front deck stamping is TO512MN. Correct to a (4SPD.) COPO
*VIN#19N 9487(Above oil filter, vertically on block bell flange) 19N I'm pretty sure is a Camaro installation?..Only the last 4 of VIN (not 6)are stamped here. I've read that Norwood got sloppy on protocol sometimes?

Thanks very much!
