A while back, there was a PYr who made up several diff stamps and was selling them for Resto use.

Did your motor have the same?

However, ours looked very similar to the one show on page one below - EXCEPT - ours had the previously mentioned "yellow paint splotch" between Pontiac engine blue painted passenger head and the stamp as shown below HERE

Note: refer to same T/A engine w OK-2 stamp image on page 169 in Gary Witzenburg's FIREBIRD!

Edit: FWIW referring to our Van Nuys built '78 W72 Stick. What box(s) on build sheet will tell build date?

Looking @ Box 1. reads:

Job Sequence Number
004267

Sched No Date
15-4267
03-16

Here's the photo (below) w the OK-2 stamp similar to that on ours...



Food for thought: Wondering out loud if the Norwood vs. Van Nuys W72 engines were inspected and/or stamped differently?

Thxs!

Reposting these posts on topic above from page 15 here on your thread Bob.

Somewhere I've a poorly lighted engine photo of ours that the yellow paint is located under the OK-2 stamp - yellow paint directly under the OK-2 stamp - and the yellow paint appeared to have been "slapped on" quickly with a brush or wide tipped paint gun as most other inspection paint splotches are throughout the GM vehicles. But until I can find photographic "proof" consider the source. .
FWIW - over the yrs when TAs were still untouched I've noted W72 engines w the 3 variations* of:

1. No yellow paint,
2. Yellow paint to the side as your included image above, and
3. Yellow paint underneath the OK-2 stamp like ours.

Suggestion: Perhaps you could PM Keith Seymour who has 1st hand assembly line knowledge and experience specifically about this? He's added a great deal of real life scenarios back stories such as in the Echoes of NORWOOD assembly line book thread...

*Perhaps the application location varied by inspector (#2, 3, etc.) and shift worked (night or day) when inspected?
