Nice!
Hard to tell, but it looks to me like the instrument panel is centered on the dashboard (as opposed to the left side centered on the steering wheel)?

There’s a interesting info in the Packard V12 wiki, stating the early 1916 cars had a 50 hp V12 because
“ Large displacement engines provided the horsepower and torque their clients wanted and due to the low quality of gasoline fuel at the time, and low compression ratios, 50 bhp was more than adequate. It is estimated that the rating equivalent of early gasoline available varied from 40 to 60 octane and that the "High-Test", sometimes referred to as "fighting grade", probably averaged 50 to 65 octane.”
The 1921 version produced 88 hp.
The third generation of cars, starting with 1933, engine displacement increased from 424 ci to 473 ci, the engine got aluminum heads and hp was 175 to 180 hp.
I had no idea gas had such a low octane rating in 1916.

I wonder if the factory V-12 could be breathed on in any degree, to safely increase performance and mileage.
To some car guys, breathed on meant adding a huffer.
To others it just meant adding performance parts.
Just now good was the metallurgy for engines?
Increase bore?
Higher compression pistons?
Cleaning up vintage manufacturing/castings?
Basically refining vintage mechanicals with more studly parts, without risk of blowing up the engine or drive train.

Also the "bottom end" (crankshaft, main bearings, connecting rods, etc.) would need to be strengthened to handle any performance improvements, and for a Packard V12 you'd almost certainly have to engineer and produce those components yourself from scratch.
I assumed the bottom end would a/the limiting factor for all the reasons you mentioned, even before the rest of the drive train.
Nice to know that the factory motor ( gasp! ) was fairly refined for the time.
