Load up the crate and engine, and bring it before me. I will investigate, install and test it if necessary, and report my findings within a few years.

Or, you can check the casting numbers at www.mortec.com.

 

638 = 350 block; won't tell you much about the motor as a whole

ZZ3 = the ZZ3 motor; the model prior to the introduction of the ZZ4; very similar to the ZZ4

 

couldnt find any specs, but 345hp is what it makes.
