you got a hp quote and dont even know which cam? find a real motor builder.
FuelMoto has sold hundreds of their 107" kits with either the Woods 555 or 777 cams. Many people across the country have installed them and dynoed them at various facilities. The results have been good for most every one of them. It's a good combination, great bang for the buck.
I'd also consider what Steve at GMR has been doing with the Andrews 54 and a 10:1 compression 107"... It's going to be a little friendlier on valve springs and cheaper fuel...
Fuel Moto's head work leaves me with a few questions. I doubt they compare with what Baisley, BC Gerolamy, T-Man, R&R, Deweys or WFO Larry can do....
But for the money they appear to be a good deal.
