Default Early build engines to late build cars

What is anyone's thought about early build engines to late build Impalas from Janesville. My 1st week of July build SS427 has an engine that was built the 9th of November

8 months? I think that's gonna raise an eyebrow or two along the way.

Is it an L72? The 385 hp engines were quite common so that would indeed be an oddity while the L72's were much rarer and done in fewer batches. I have seen LS6 engines built well before the car's build date so you never know. 8 months is quite a stretch however.

Who knows with an engine option that wasn't in high demand. If the casting date and build date are in line, the engine could have taken months to be used in Impala inventory. They may have wanted to clear out the L72 inventory for that model year and used it in a car. I wouldn't discount it completely.

Isn't July to November more like 5 months??

From conversations I've had with GM employees, they didn't necessarily rotate stock in the factories. Pallets of engines could've easily sat while new ones came in and got stacked up in front. 1 or a few could've gotten trapped in a corner.

Our 68 SS427 from Janesville was built 4th week of July and the engine was assembled January 11th so that did happen.

It's actually 4 months, but we are talking about November 9 1967 to 1st week of July 1968, and that's darn close to 8 months.

But as per Warren's example above, which is over 6 months, it would appear to be possible.
