Question Cam Selection for 110 Motor

Any thoughts on a camshaft for a SE Dyna with the 110 motor? I have looked at Andrews, HQ, and Woods. They list cams for 95-103" but nothing for the 110" motor. I thought a Woods 9 with an increase in compression (shave the head) would work well. Or a TW55 in the Andrews. The motor is listed as 9.3:1 now, should be able to get 9.8-10:1 with a cut on the heads and a zero deck dont ya think? Already have played with the maps using the SERT, seems to be running well, only have aftermarket pipes right now. Plugs show very light tan color which is amazing with the unleaded. Rear cylinder runs cool 200-230 range using AMSOIL in all holes. Will increase the size of the throttle body also, or go to an aftermarket piece on that too. Crank runout is .0015 right now, and everything seems ok down low. I know, the cranks are crap, etc. etc. but I am not going to split the cases right now. Will wait to see how the longevity holds up first before the crank comes out for a balanced and welded model. I dont purposely beat on it, although occasional run through the gears with limit of 5500 on the tach. Planning on a 30 tooth gear on the trans. in the future too, to help with the too high of a ratio on the stock 6-speed.

Input appreciated,

BigMo

As for as cams go it all depends on how much your willing to do to the valve train. I found that my 110 really liked the S&S 640, but I have done quite a bit of topend work so I'm not sure how the stock valvetrain will handle it.
I have just replaced that cam with a custome Andrews, ground to my own specs. I hope to crank the engine for the first time tomorrow morning. I'll probable go to the Dyno next Monday to see if I made the right move as for as the cam is concerned.

The TB change to a 50 really helps the 110, prior to that it felt like it was breathing through a straw when I'd roll on the throttle.
