First 1967 383 installed in a Barracuda

Hello to the group,
Does anyone have concrete info on the first day the 383 was installed in a production 1967 Barracuda?
Many people have opinions, which is fine, but that's not what I'm looking for.

I read one article (can't find it now of course), that the first day of production for the 383 in a Barracuda was March 01/67.

Because of the sheet metal/sub structure change from 1966, there was tooling delays and the first production Barracuda wasn't built until November 25 or 26, 1966.

Because of Ford and GM having big blocks in their smaller cars, Plymouth was late in joining the big block offerings.

I believe Car & Driver did a road test on a pre-production 383 Barracuda in August/September 1966, but this wasn't available to the public yet. Also, most all pre-production cars ended up being crushed.

So if someone has good info on the first build of a production Barracuda 383 Formula S, I would appreciate where their source is from.
I have a 1967 (all original car) sport hardtop, 383, 4 spd, with a build date of March 01/67 and a very low shop order number. I also have the IBM data card from FCA.

Any help would be greatly appreciated.
