Tom & Paul:
The motor is basically stock, bored 30 over, hypereutectic pistons, stock compression, stainless valves, Comp Cam w/ 265 duration + 1/2" lift is all I can remember without looking it up.

The blower came from a local wrecking yard ($200), supposedly had 60k miles on it. The rotors had no apparent wear. I took the front snout off, mainly to change the pulley size, so I changed oil in the gearcase at that time. So it has not been rebuilt.
