Joey's 42 Fountain. Motors dynoed out at 1298 each. He might want to buy those two-barrels from you CruiserJohn...I can't imagine 1300 hp is gonna be too good on gas...

Don`t know this Joey but someone should mention maybe upgrading to Bravo XR top cap might be a good idea haha

Wow, was Ken sent me that last dyno sheet. Den, if those AFR ratio numbers on the right are correct, that is WAY lean for it to survive in a boat. Those numbers need to be in the low 11's, in my opinion. It may fatten up in the boat, but I dont think two full points. I'd rather have to pull a jet size or two out when installed. Wednesdays pulls were showing we were going in the right direction jetting it up, when the dyno broke. What happened!! i would be concerned with those AFR numbers on a N/A 502, let alone a 15psi blown engine. 13.7? Thats getting a little too close to stoich. A 2012 Ford Escape V6 would probably have a full throttle AFR reading similar to that.
Two things I would do. Make Joseph spend a few hundred and take his tails to the welder, and put 02 bungs in them. Then, borrow a wideband and check while running the boat. The 02 wont lie, and I wouldnt trust plug readings on a 1300HP marine engine. Second thing, drop the boost to 10-11 PEAK psi. It will still make 1100HP. Im not sure how much cylinder psi those MLS headgaskets can withstand?

The thought process was, with marine exhaust, and in an engine compartment at 120 degrees and 80 percent humidity,,,, it is going to fatten up.
And your right,,,,,I would have an 02 sensor on it if it was mine.
Remember what I said in the beginning of all this !!!!???
I have no opinion,,,,,give me a complete motor and I will rig the boat !!!!!

I hear that. I'd still rather see it jetted perfect on the dyno, then pull fuel when in the boat if needed! But hey, they aint mine.
Here is one of Eddie youngs 1025 EFI engines. Take a look at his boost numbers, and his AFR readings on the dyno. 11.8 at full tilt. Thats with dyno headers too. He does usually tune after installed in the boat, with a wideband. Maybe thats why Eddie doesnt have comebacks on his engines though. Him and I were talking a few weeks back regarding valvesprings. I had asked him if tool room springs were worth the money on something like my setup. His reply was "I just got a set of my 925's that make around 950HP in for a freshen up. 350 hours on them and the crane springs tested within 5psi of each other, so I'd say the crane's would be just fine for you"
350 Hours from a 950HP blown marine engine before a freshen up?!! Works for ME!
