440 and 727 for sale on marketplace

Found a 440 and 727 trans for 500 obo. Complete and all stock. The motor allegedly has a 440-1 stamp on the block. Out of a 76-78 motor home. Is this a decent engine? I'm wanting to bore and stroke it to the max.. looking to do a high compression. Nitrous engine.

Good way to go , no trans alignment problems . I gave $500 for my 66 440 w/ trans still bolted to it .
