I think a cam with duration in the 230* range at .050 on a 110 LSA would work nice with the rest of your combo (including rear gears and manual tranny). If you go too much shorter on the duration I don't think it will make power where you will need/want it. You don't need a bunch of low end with the gears you have and a stick. Go with a nice solid flat tappet with the above specs and you will have a blast. Keep the lift right around .500 - .525.
