I START WITH THE TIMING 36 DEG @ 3000 RPMS TO START, HAVE YOU CHECKED THE ROCK GATE ON THE INTAKE OR EVEN TOOK A LOOK UP IN THEIR. 
LMFAOOOO! THAT IS JILAROUS!!!!!!
Boost has many great points there though. Gotta read in between the caps........
If you were outpowering the 'cuzzi, rpms would be off the charts. Seems like you have a problem powering the pump to begin with, to me. So Boost is making the correct diagnosis that the basics are screwed.
FWIW, Ralph's expertise not withstanding, I've seen some VERY hot running Hondo's out here locally and cannot say it's a "crap" hull. Moo held her own last year, This year Pickles done fine for a 350 or so HP BBC, but quite a few Hondo's (and others) have handed me my ass this year playing around. Some of those I know for a fact woulda handed Moo her ass similarly even were she even running right (Flytime was in Moo to hear the pop that was the indicator something was seriously wrong at the Tom Papp deal, little did I know, and two trips later it REALLY reared its ugly head).
Anyway, unless your pushing well over tha 5k rpm line, the pump is NOT the problem. And could very well be, as Boost pointed out, a tune issue to get to that point where the pump IS the issue. Even then, your 'Cuzzi can be worked to handle this. The work involved in switching, well, I'll leave that to Tom or JIm, but ain't cheap. Then you still have to build a different pump that you were gonna build anyway.
