Looking at some of the cam specs for engines like the 120R... zowie! Big ol' cams in these things. .658 lift? 262/266 duration? Still, the 120R makes good low end grunt too, like 100 ft-lbs by 2500 rpm. Considering the big valve, big cam, and modest 10.5:1 compression ratio it's amazing how streetable and torquey these "race" motors are. I guess there really is no replacement for displacement...

I stole this 120R graph off another HD forum (don't sue me). Look at this monster:




136/138 w/low end grunt like that amazes me after seeing the cam specs.

I'm feeling all inadequate with my little baby .495 lift cams... After hanging out with the big inch crowd on these HD forums I might need therapy.
