727 Identification - Help - 68 Barracuda 340 Block

A couple of pics would be helpful, also...
That said, if it was an original 727 for a Jeep, it'll have the AMC bolt pattern bellhousing which renders it useless for a smallblock Mopar.
Chrysler built automatic transmissions, both 727s and 904s, for various other manufacturers over the years, as well as versions for their own use on small blocks, big blocks, and slant sixes which are all dedicated to their own engine family.
Sorry, I couldn't find anything on the numbers you listed, maybe someone else will have better luck. Chrysler numbers are stamped onto a pad just above the pan rail, usually starting with a "PK"...
