Congrats.  That's a lot of RWHP without power adders, especially since your
cam is pretty streetable and you're only running 11:1.

Now, go out and make us some tire smoking videos so I can live through you
(while my car is down).

Will.

On the Engine Dyno Pulls:
Final adjustments at HMS Performance in Whittier made 

485.8 RWHP @ 6,000 R's
459.3 RWTQ @5,500 R's

Yea, we have the dyno sheets. Definately there was and still is adequate
free play on adjustment before we ever got to the dyno shop. Dick and the
guys in the shop know what they are doing. It wasn't set it up too tight and
Drenske has set the Centerforce up the last 2 times. 

Definately its also the right Byers Precision Pro-Formance supplied Pantera
specific dual friction Centerforce assembly.  Dick also set the new assembly
with the old side-by-side. Drenske could do these blind. And yea same-same
throw out bearing. 

Talking to EriK Belter and Dick Drenske and Harv the guys at HMS they're ALL
convinced  that the Centerforce just can't cut it on serious power for long.
These guys as you know Mike are all pro's. I told them you said it wasn't
set up right and they said something about kicking your ass...I think they
were kidding! ;-]>

In summary the feedback from JT,  Erik and others is forget the Centerforce
and forget  the triple disc clutch but definately  go with a double disc
McCloud..

 Were you using the Pantera specific Dual Friction Centerforce assembly?
 
 
 And much more importantly, are you *sure* you had it adjusted correctly?
Even a little bit of pressure on the throwout bearing caused by an
improperly adjusted slave cylinder would cause the clutch to slip (and
drastically shorten the life of the throwout bearing).   Before going any
further (and more importantly, before spending any more money), absolutely
ensure that there is adequate freeplay in the clutch mechanism.
 
 Although the Pantera Centerforce clutch is a 10.5 inch unit (the stock
clutch is 11 inches), I seriously doubt that it's incapable of withstanding
the torque that your motor is putting out.   If it's not misadjusted, could
there be an oil leak (either from engine or gearbox) or some other problem?
