A race engine would have in excess of 12:1 not run on pump gas and would not be able to tour the country.

Sounds like the best of all worlds - a touring drag-race engine! It is however designed for life on the rev limiter, which is the point I was making. It won't last long doing that if the crank run-out is not spot on.

Interesting thread 
I'm doing the 120R hopefully by the end of this week, or for sure by the end of next week!
My local Dealership, Treasure Coast Harley Davidson Stuart, Florida is doing mine. They have done over 30 of them, and tells me they have not had one problem with one! Furthermore, they offer a full one-year warranty through their dealership on the engine; parts & labor!
I'm looking forward to the new engine!

S&s 124
My S&S 124 will be in this week and should be back on the road the first week of March. I chose the 585 cam as I do not want to get to radical. We will be putting a Primo Rivera Pro Clutch in along with new 58mm throttle body. I chose to use the Pro Tuner as the brain for this thing. Will be prtting Lyndall Gold Pads and thinking of putting new brake rotors.This all will be put on a 2007 Road King running Vance and Hines True Duals. If anyone has done a similar installation would appreciate any advice and also about the HP and Torque I can expect
