Hmmmm...
Thanx Formulafastech.
The guy at the Avanti manufacturer down the road says he has one that is a "2000 model year with 128 hrs." Someone is buying the boat and wanting to put his own motor in it. I was thinking about swaping my 502 Mag MPI with 329 hours on it for the HP450 instead of doing a refresh on the 502. What would you do???

On another note.
What would be the best way to pump a 502 Mag MPI (all stock) up to about 450 hp from the 415 hp rating????
Headers??? reprogram ECM???
I don't want to get crazy or spend a bunch of bucks. Just want a little more performance while retaining reliability.
