Well, Tom Graham and Charlie Volkenng did it again...they completed the rebuild of my engine. This is a video of the dyno test and results last sunday. These two know their stuff.

Very interesting.
Yes, interesting ;) What's inside that engine? Original, reground or Stipe camshaft? Z head?
Looks to have a "Z" head. The numbers are impressive. My '27 put out about less hp and torque in tests on the MN tour, but the testing was different.
All the tests there were on the same dyno, but with wheel drive as opposed to the 'bench' stand, so you get real world hp 'at the rear wheels' where the tire meets the pavement!
Tom's machine
My results, Stipe 280, Z head, .060 over alum pistons, magneto/coils ignition.
18.88 at the rear wheels
The engine has oversized pistons, oversized Chevy valves, Chevy rods, indexed cam (balanced) and a high compression head. They also ran a distributor for the test. I imagine with the old timer and coils the numbers will go down somewhat. Tom did mention that it should have around 28hp after break-in, he also made the comment that it was a "good engine". Don't know what that means but I like it....
What was Prus's '22 Touring running?
Roar
Don't remember or maybe it was a secret? Some of the faster tour guys just like to keep you guessing what they have over yours
This post on the Int'l site showed what most stock T engines turn at the rear wheels under dyno testing.

Summary Report

From memory, if the T ran more than 20hp at the rear wheels, some stuff was done..headers, carb, A crank or rods, etc. One of the overhead T's ran more than 36hp at the rear wheels.
