Here are some of the Manufacturing and scheduling issues that could cause date abnormalities with drivetrain components at Norwood.

A QA/QC hold at blocks at the foundry, or at the Mfg plant. (Flint MI or Tonawanda NY)

Scheduling or logistical problems with the rail road and inclement weather (snow storm -floods-mechanical rail problems)

Railroad strikes, teamster strikes

Strikes at the foundry or the Mfg plant

Problems with Logistics and Application 35 lead time build scheduling. Errors here were miss counts and just Having enough workers to get the rail and trucks loaded and then unloaded timely and in the build system to meet the established production schedule. No bar code scanners yet it was a manual count. </div></div>

Phil,
Most of those scenarios you mention would result in an engine arriving late and holding up the scheduling of the car, rather than arriving earlier and sitting around for months before being installed in a chassis. As you know, a sequence number wasn't assigned until the inventories were checked and indicated that all the parts needed were at the plant.
Of course, by &quot;QC hold&quot; you may be referring to an engine failure at test run, requiring a rebuild and a delay which would result in an engine with an assembly date much earlier than the car assembly.

Verne,

If a block is held due to an issue with AQL that could be at foundry, or an issue with any number of suppliers including TRW. GM did not like scrapping anything and even had a salvage department in plant to recover and reuse damaged parts. These would be engines with a casting date or in some cases an assembly date that would be vastly earlier than the car that they ended up in.

No I do not know about &quot;sequence numbers assigned until the inventories were checked and indicated that all the parts needed were at the plant&quot;.

Let me explain...If things were running on time and there were no labor stoppages ongoing a block could be cast and assembled early in the week and make it to the plant at the end of the week where it was unloaded and sent to the line the same day it arrived.

This was what &quot;Application 35&quot; controlled. At Norwood the specific parts for an individual car were not even in plant at the time the key card was punched and the ramp up parts arrival timing was evaluated at the joint Fisher/Chevrolet production scheduling meeting which occurred 72 hours prior to the build out day. In this meeting the all production was reliant on the Application 35 production forecast for inbound materials. Even at this time it is very likely that the many of the individual parts for a car are still not in plant yet and this is 72 hours out from the build day.

I should have said &quot;presumed&quot; to be in inventory by the time the build was scheduled. I understand the process. I'm sorry if my statement was misleading.
