Made in Mexico crate motor most likely it’s a 350 truck motor of modest cam and compression. Check the head casting numbers and get back to us. They're under the rocker cover about in the middle of the head. The 010 casting is a good heavy duty piece, check it out to see if it's been rebuilt. With some modifications these make a very reliable high output engine.

As Bogie said it's a Target Master replacement crate motor manufactured by GM of Mexico.

These are low compression 75 cc open chamber heads originally used for 1968 through 1979 production, but they have soldiered on in the Goodwrench/Targetmaster crate motors.
