Mine was built by Simmie Green and I have 275 miles on it now. What happened to that one of yours by him??

And your second one has a coolant leak? WTF....

It's interesting that every one of these signature plaques has the right hand bolt not even close to centered in the slot. Either the mounting bosses are not properly placed on the manifold, or the plaque holes are not properly placed. This is so sloppy. GM's quality...

The left side is not slotted, the right side is slotted. Can you imagine a fraction of a milimeter machining problem on 2000 cars with two piece manifolds with the potential for variations in gaskets and center butterflys, etc? I bet all the cross threaded bolts would be even more frustrating.

These are UAW members who assemble engines. Some of us seem to be equating these people with professional engine "builders" who spec and blueprint high performance motors for racing etc. Not sure that these signatures have much meaning at all.

Every party needs a pooper, that's why we invited you.

UAW members they are, but as with most line UAW jobs at Bowling Green, you have the same task that is completed in less than 4 minutes until the next same thing occurs again on the next car, I would think you become expert at a very simple task or replaced or reassigned. As for the engine builders, about 3.5 hours to build a Z06 engine for example and not handed off to another builder if you don't complete that engine it waits for your return to work. Again, doing the same task could lead to an expert at that engine vs. a high-performance engine builder that does many different types of engines. As far as spec, handled by GM's professional design team and they got 670 hp out of 5.5 naturally aspirated, nobody else has. As far as "blueprint'" a new virgin block that is decked and it is balanced as well as heads cc'd, so what is left to "blueprint"? Not resizing connecting rods, not shot peening forged rods or using better rod bolts, maybe a new titanium new rod is blueprinted so to speak.

To me different than a line engine that is mostly robotically assembled and shipped to be installed like the LT2.

I appreciate that someone might have a sense of pride in assembling an industry leading engine not assembled by a robot and take pride in their assembly - just a perspective.

That is a very good analogy, I know I’m very pleased with my engine builder and engine. GM and the UAW have done an outstanding job on the Z06.

The very fact that a buyer can walk in off the street and assemble his own engine with no prior training and a UAW worker at his side gives you a very good idea of how much expertise is involved here.
I would prefer to have the name of the lead engineer who handled the design and development of this motor on the little badge and not the hourly person who essentially puts the square peg in the square hole.
This assembly protocol has obviously been made idiot proof to the point where a lay person can be hands on involved in the process.

I understand that the left side is not slotted. What I am pointing out that the right mounting is so far off, that even the large bolt head can't cover up the huge amount that the plaque holes and the manifold mounting differ. It's not even close to centered in that slot. This plaque is supposed to denote hand craftsmanship, but the plaque itself says "sloppy".
