The 8270 & 8273 were used on all the Ram3 engines up through at least Feb 69 production.
The 69 units had the date codes stamped into the baseplates.

Something went goofy about Ram3 and Ram4 production releases.
The Ram3 didn't start going out until around late November-December
The Ram4 didn't start going out until around late Jan-Feb
And that just applies to GTO's

The Judges were another month or so behind those dates in both respects.
I think the first Ram4 Judge known is around late Feb or early March

Its all weird.
Best guesses are maybe the Induction set ups weren't finished yet.
We know the Ram3 Judges were timed/planned releases.
But why the Ram4 Judges were prolonged is odd , maybe they wanted all the Ram3 Pattern Judges gone first.
