I think this experience, more than any other, has taught me how valuable 
a dyno experience can be.  I know a local car guy who also owns a 
Pantera, who has a great shop and a home made dyno.  It's more of an 
engine test stand without all the fancy HP and Torque equipment, but 
nonetheless, it's a great idea.  It's what he uses on all his engines 
prior to installing them in the car.

Great photos.
