here is the response i got from dan last week on the setup.
We just got off the dyno yesterday and with Shearer In-frame pipes, 35 PWK, V-Force and our domes on pump gas, motor made 90.53HP and 48.34 TQ on pump gas. The power curve was very broad and very rideable- these cylinders are the real deal! +4mm stroke 68mm bore Cub, 421cc. Not much work at all in the cylinders. Basically cleaned-up porting. Shearer in-frames, 35mm PWKs, V-Force, 155# of compression on pump, timing at 4 degrees. We expect the stock stroke stuff to make 83-85HP.
