340 cam

[USMC67DART]

I recently purchased a 340 dated 6 1967 for a rebuild. I would like to find out what cam was in the motor. Have no idea if the motor was in an automatic or stick. If someone could help i would appreciate it very much, the marking on the cam are as follows.

One end 657 10
other end 236 mex

am willing to sell if some one is interested
thanks for the help
