Hey Danny,
You're just down the street from me! August 5th is the next
RAT breakfast. I'll be there, everyone knows me, so they can point me out to you.
The difference in HP/Torque between the Speedmaster and the America isn't enough to make a huge difference. That being said, the most important differences are personal prefrences.
The seating position being the biggest one. Get over to Cascade Moto Classics (tell Bob, I said Hi) and sit on both. The America has wider and higher bars, the Speedmaster slightly lower and much narrower bars. The Speedmaster has an all black motor, the America has the silver motor. The paint schemes are different as well.
Then there is the cost differences. The Speedmaster comes with a tach and dual front disc brakes.
Both bikes are absolutley awesome and you won't find a better cruiser on the planet.
