You need to get the numbers from the flat pad on the RH side by where the alternator is mounted if it's a Chevy V8.

That is what tells you the Vin # it was installed in, and application details.

Just go to www.google.com when you find the numbers and type in "Chevy engine ID chart". You'll get more than you can shake a stick at.

CJB might be a partial assembly suffix code, a GM dealer's parts counter could easily verify that in the microfiche/computer.

It is probably in the place I stated for this V6 as well.

I dont know about newer motors but most GM V8's have the block #'s which Identifies the engine cast into the block right behind the drivers side cylinder head where the tranny meets the block. Maybe your V6 has a # in this position also?

Simply bring what you find to any GM dealer and they will look Group 0 of the Astro/Safari parts catalogs they have. In the front matter, they have what codes are what year and displacement.
