Except for the 600SCI, 575SCI, SC600 you are right. If we are counting stuff that is close to 600HP, the 525EFI's routinely dyno 540-550 & higher. The 540 Bulldog, HP500, HP465 all ran on gen 1 bravos as did the SC600.

Orlando, just try some of Don's TRS's & see what it does. For a few hours & some wrench turning you would KNOW if they will work on your boat rather than listening to some of the BS people on here spout off.
If I would have listened to all the people on here that said my boat wouldn't even get on plane with -3" drives on 12" boxes I wouldn't be running 94mph right now.
Your best bet is to try the TRS drives Don has or go to Konrads & spacers. I think that finding a II is going to be tough & expensive.
Put a $$ amount on weekends off the lake due to broken parts & reinventing the wheel.
There are men on here that have tons of dollars & thousands of hours of experience making things better with drives. Trust the ones who have invested the $$.
My choice would be Konrads. I would sell what I have & go that route.
Also our friend with the Cig only has 600 a side. Don't let him BS you.:grinser010:
