Hi Guys,

Guess I must have time to spare, since I've been looking at old posts in the Forum.

About time I answered the questions posted by Judson and Jim - guess I did not have the trigger to "Notify me by email when replies are posted...":

Cams are special ones ground by Richard Reyman at West Coast Cylinder Heads in Reseda, CA, when he built the engine.

Below 4000 rpm, the engine is just fine - lots of torque (well, enough for me).

The hp and torque curves posted are Crankshaft values.

Don't blast me for using cheap spark plugs.  Fact is that plugs that wear actually throw red hot debris (think of spark discharge machining) into the cylinder, helping ignition.  So, in this case wear of the electrodes is good.  Replace them every 2-3000 miles - they only cost about a buck each !
