One of my friends owns a speed shop and usually brings the chassis Dyno in every 6 months or so and that will be when I do the testing.

What the eventual plan is to set the engine up initially as a carbureted Poly (probably using the Tri-Power)and then get it in a car. After doing the dyno runs, the next step will be to change the carburetors out for fuel injection (having 6 months in between tests will work out well). As I suspect the configuration I will eventually end up using will be the Hemi Heads and fuel injection that will be the final change.

I'm really as interested in the Torque results as I am the HP numbers. Comparing factory numbers on the standard 1956 300B 354 to the 58 4bbl 354 Poly shows some interesting results. The 300B engine made 340 HP and 385 ft lbs of torque. The Poly made 310 hp and 405 ft lbs.

It should be interesting.
