You might want to reach out to a few folks and ask, I am sure Fuel Moto will help.
Heck I had my 110" performing a great deal better than the advertised HD dyno numbers for a 117" kit, it was running TW 777 cams, Stage 1 head head work, FM 2-1-2 header w/eseries and dyno'd by Jamie and it performed.

The problem with the 259E cam in the Kit is not the cams fault. That cam real needs 10.5 compression to come alive and make torque down low, and power at the top. I had a 110 with 10.8 pistons, head work, 55 HPI throttle body and 5.3 injectors making 124 toque and 123 HP. Torque was over 100 at 2400 rpm and a nice flat curve.

The same motor has been built to 117. Did not use the HD kit as compression was way to low. Seeing I had to have custom pistons made when I did this last spring, I decided go go even higher on the compression, 11.4. Seeing I did that I went to a woods cam TW-9B-6. Very long flat torque curve, 140 peak, but over 110 at 2400 rpm and 120 by 2750 rpm.

Key is matching compression and cam.
