That's pretty cool. Be a good engine for a boat.

What do the numbers mean? I figured a 4-71 would be smaller...

Nic
The blower designations came from the original  GMC diesel engines they were used on..
 .. the 4-71 was a blower that fed a 4 cylinders engine of 71 cubes each..
the 6-71 was used on a 6 cylinder engine of 71 cubes each..
Later designations and case sizes were never used by GMC but continued to use their numbering system for reference.

It *is* smaller Nick, check out how short the case is.
