Outstanding is right.  It's so outstanding that I tend to put it in the same category as the other info he has dispensed  (I.e., smoke).   I could be wrong though.  All things being equal, the P Port motor should make more power than the sideport engine.  Just not sure it is THAT much more.  Everet Hatch was able to make a little over 210 HP at 6000 with carefully tuned long p-port runners after much R&D.  I do believe those numbers.

That is outstanding HP, even on a California dyno. Any port pictures or porting open and close figures?
 
 Sounds like the one to replicate. A typical Weber intake system from a race shop would be quite short. Not ideal for 6,000 RPM. Better at 9,500 to 10,000 RPM,
looking for 335 HP.
