Helping a member bolster his argument on the date the 273 was made available to the Valiant/Dart platform. We know it was a 64 offering, but was it a 'mid year' introduction, Jan 8, ie. April 64's "Barracuda" ? Seems cars were built Aug 1 of the previous year to start the next years model run so April was almost a 4th quarter intro with only 3 months of post April production until the 65 model started down the line. I have a 273 cast:

Nov 20 63

no idea when it was sold or offered but It was cast 11/20/63. Check you stuff and post them dates (no June or July dates expected)

The 1964 FSM for the Plymouth/Valiant line did not include the 273, only the 6 Cyl motors in the Valiant line (unless the absence of the "6 Cyl" for the Signet means a V8?)

The V8 Valiant models are not covered in that printing of the FSM; if they were, you'd see listings for VV-2 models ("1" = 6-cylinder; "2" = 8-cylinder).

A data point: the 1964 Valiant and Barracuda ordering code list dated 16 April 1964 refers to cars with 8-cylinder engines, so the 273 (2bbl) was available at least as far back as that date, possibly earlier.

Dan! Do you have this listing for 65 Dart?

Per the Valiant.org website, the 273 was designed for the Valiant. It went into production in December of 1963. Your Nov block could have gone into a Dec or Jan produced vehicle. The block should have an assembly date stamped on it.

The assembly date is February 26. But for a power pack engine! I was thinking that it might be one of the test mules with 273 x 4 bbl. Like a Charger 273 or Commando 273!

Thanks @pishta. This is a interesting discussion. I had always heard and thought that the 273 started production in the 1964 model year which starts the first of August. Now that information is surfacing, it looks like it didn't hit the streets until around the first of the year (1964) so it could actually be a mid year release. I like to learn and I don't mind being proven wrong. That's what keeps the hobby so interesting. Keep the info coming fells! Thanks.
