Thoroughbred are a pain in the ***.The bigger you go the faster you blow. When they go fast you race, racing kills.The more moderate cams could save the bottom end for a little longer.Race cars are pulled down often and pressure points replaced. I want a reliable ride . Eighty is about all you can get away with on the highway . Race bike drive till broken fix, play more. Our thoroughbreds were fast but they all came with a doctor attached.

 

Considering 120 or Trask Turbo. Turbo is less money, more power (and right where you want it at low to midrange)

 

I much prefer the look fo the 120 motor to a bike with the Turbo. Just my .02

Just wanted to say I'm jealous, I'd love to have a 120R. I'm sure it will work out - and the reliability is probably going to be better than a stage 4 103" but with more mid-range. Enjoy it.

 

I just saw that JIMS has released a 135" twin cam motor... Just sayin.
