Look on the front passenger side of the block in front of the head, there is a machined surface with stamped numbers, the first three being the engine size. Also be sure to visit www.6066gmcguy.org. Great site for GMC owners...

So what engine do you have?
The V-6 engine has the model and Serial number stamped on the top of the block just forward
of the right head. This number will help you know what size & series engine you have,
as the displacement and model are the first part of the number.

Sample number, 305E 387218.

This is looking at the number on the block .
