693 HP and 723 ft/lbs of torque
Just got off the phone with Mark at Precision marine, the 540 that I built is making 693 hp and 723 ft/lbs of torque. Guessing that it should make my 1999 Donzi 26 ZX move pretty good.

That is good news. Welcome to the fast 26ZX club. What kind of speeds are you wanting?

I am running 1/2" all the way through. Eddie Young made a custom return line to the tank. There are some pictures posted on Boatfreaks.org Let me know if you can't find them.
You are going to have fun!

It is a stock Gen VI 1999 502 block. I had it bored .032 over and had a Cally's forged rotating assembly installed. I had the stock heads proted and polished. I am running Marren's 60 lb injectors, Custom ground crank that was spec'd out by Mark at Precision. M1 Procharger running Approx 5 psi of boost.
