My question is:

What is the difference between NOR and LA built Z-28's

Did the two factories use the same "exact" parts to assemble the cars ?? I am asking this because I am looking into Intake manifolds and I see that some of them have the "snowflake" casting on them...Is it because cars built in Ohio had them and LA did not ???

Thanks...

they both should have the Winters foundry (snowflake) on them

[Vintage 68]

I have never seen a 1969 VN/LOS built Z-28 without the #3932472 Intake with a Winters Industries 'Snow-Flake' Logo on it. I don't know if anyone else ever cast these intakes for GM.
The 69's used the same style aluminum intake as the 67-68's (#3917610), but didn't use the Oil Fill Hole in the front (it was plugged) or the Bypass Hose (also plugged). There was a slight difference in the location of the Thermostat Hole for 69 also - it was centered on the Intake instead of offset to the Left or Drivers side of the manifold.
Hope this helps - post back with the casting numbers and dates if you can.

Just trying to see if I can get this back to "bone stock"........

Both Camaro assembly plants were serviced by the same engine & axle plant.

Other than VIN stamping and PTB stamps I know of no differences between Norwood and Van Nuys.
