Will those who cureently have or have had experience with 107, 110 and 120 motors please tell me what you do or did like about them, as well as what you don't or didn't like about them? I've heard that the hp and to numbers from the 107 with heads and cams will exceed that of the 110 and be in the same ballpark as a 120. Lastly, which motor is better from a reliability and longevity standpoint? I'm sure I'll be happy with my 107 when it's complete, but can't help but wonder if I should have gone bigger. Thanks

As they say: "There's no replacement for displacement" Build a 120 with the same heads, cams, and compression and you will have more than a 110 by 9% or about 10 more HP and 10 more Ft-Lbs of torque. My 120 runs great!!
Harley has been building the 120 motor for six years now. I expect it to last. The 259E cam in the street version is easy on the valves and lifters compared to the the high lift cam in the race version of the motor.
