I cant find my tag ? I have a 2011 carbon. Fast intake, Possibly aftermarket heads ?
Is the tag on the head or tunnel ??

[QUOTE=BJ67;1586675228]That's me brother!

After working in GM Engineering for over twenty years I built Corvette engines at Wixom PBC for over six years. Enjoyed my time there for sure. Great group to work with and how can it get any better than building high performance Corvette engines? Also got a couple nice trips to SEMA and even went to Barrett Jackson in Scottsdale.

I hope your LS7 has served you well. Someday I hope to buy one of mine too. That would be so

I'm now working at the GM Proving Ground near Milford. Working with Durability vehicles, mostly future stuff. But do miss my days at Wixom sometimes...

Oh by the way it's Henley (no s)

[QUOTE=eaglei;1586678197]Sorry Mr Henley, my first name is also Don. The lS7 seems to be a good one

Tag is probably still on your stock IAFM (intake manifold).

Tags have been shown on many postings here. Located on topside of fuel rail bracket on RH side of manifold. Here is a recent picture that shows it.

Hey Don,
That intake isn't in your garage is it? Against company policy to take samples...

Does anyone know how to decode these head numbers ?

GaGlen

Okay, just bought a one owner 2011. Donald can add another mark to his column.

eaglei

12578449 looks like a GM part number. Not sure if others are casting number, head serial number or what.

There should be a EUN number on the bar code label on your LH cylinder head. This number can be decoded to give build date and other details. Here are a couple pix reposted to show this label (there is also an identical label on rear of LH head)

Thank you .

I have ZAS on top than looks to be 10z?s 321231140

Here's your EUN decode

ZAS = 2011 Model year LS7
32 = Built at Wixom PBC on line A2
123 = Julian build date = May 3
11 = Built on A2 during 2011 calendar year
40 = sequence number that day. You may want to double check this as 40 engines from one build line would be unusually high.

Enjoy your fine ride!

You are correct the last 2 numbers are "10" not 40. hard to see...

Thanks for decoding !
The car is a carbon edition with some tasty mods. Love it !!!

eaglei

Thanks for the posting sir!

Will add to the tally on next update.

Hope she serves you well and puts a big grin on your face. :-)

Had a Corvette Forum request for final production numbers from Wixom. So I did a little digging and here's what I came up with by each model year.

2007 LS7 (Z06) 8,159
2008 LS7 (Z06) 7,731
2009 LS7 (Z06) 3,461
2010 LS7 (Z06) 518
2011 LS7 (Z06) 904
2012 LS7 (Z06) 478
2013 LS7 (Z06) 471
2013 LS7 427 Convertible 2,552

Total LS7 Corvette 30,546

2009 LS9 (ZR1) 1,415
2010 LS9 (ZR1) 1,577
2011 LS9 (ZR1) 806
2012 LS9 (ZR1) 404
2013 LS9 (ZR1) 482

Total LS9 Corvette 4,684

2011 LS3 (GS) 1,699
2012 LS3 (GS) 1,628
2013 LS3 (GS) 1,515

Total LS3 dry sump GS 6,310 (manual shift coupes only)

Total Wixom PBC Corvette engines 41,540

Note: This total does not include crate engines (either full builds or long blocks).

Numbers as interpreted from Corvette Action Center website. Cannot verify absolute accuracy.

That 08 manifold is a result of a H/C mod on my car,old heads were o.k. Thanks for a great Ls7 Chuck.

Robert Vernier built mine and I am sure it was built as well as all of the others.... That Robert built.

Mine made 487rwhp with Headers, exhaust and carbon Super Beeline 112 and a tune.

Thanks Robert!

Hib Halverson

Hey Don, just to confirm, you're estimating the number of engines based on vehicle production numbers by MY which you found on the CAC web site?

erikszr1

hey whats up I just realized you responded to my post! thanks again, I hope all is well. So tell me more about your ride? just curious, thanks!

eaglei

Hey Hib,
Yes my numbers are based on CAC production numbers. I assume they are credible but would certainly invite verification.
For some model years it takes a little digging to seperate Z06 from ZR1.
Also this summary does not include crate engines we built, mostly H61's. Wouldn't be surprised if they could take the number up by 10% or more...

Here's a link to my spreadsheet.

Hib Halverson

Thanks "eaglei".
How do you like the new job out at the Grounds?
