The cam change is fairly easy and inexpensive. The big bore kit is a lot more labor intensive and more expensive. Guess it depends on how much bang is in your buck
Don't think you are going to take your stock bike and turn it into a 100 HP monster by adding a cam, replacing the carburetor and putting on straight pipes. Getting an 80 inch Big Twin engine to produce 100 horsepower at the rear wheel is difficult, time consuming and quite expensive. You are much better off bolting in a Crane Fireball 310, an Andrews EV-27 or a V-Thunder EVL-3010 in your street bike than trying to find a long duration cam because you have been told 'bigger' cams makes more horsepower. A well designed and tuned engine combination, using a mild bolt-in cam is quite capable of embarrassing most other Harley's between stoplights. 100 horsepower is not very useful if the engine does not make power until 6000 RPM. Harley-Davidson Big Twin engines were not designed to take that kind of abuse. An engine with 70 HP at 4800 RPM and 85 foot pounds of torque at 3200 RPM can be a real thrill compared to a stock EVO motors.Just an opinion.

If the OP is asking about that 2010 in his sig then its 96", not 80", and its not unheard of to breech the 100 mark in TQ and/or HP with a cam + stage I.
I have KN filter on screaming eagle backplate, CVO power core slip ons, no cat, and currently have DobeckTFI. I am thinking of adding Rev perf EMS and maybe S&S cam for right now. I want a bottom end cam, nothing ratical. My next move will be 106 big bore kit after that.
