ive been thinking the same thing as SS930 and lil red about the fuel system....wow

Those pics look strangely familiar.......

that's a lean condition, not enough fuel + too much timing

meaning . . . bad tune, poor fueling

you dug deep for that thread....

look at this almost 400 posts , crazy

I haven't been able to get away from that boat even after I quit boats. It is in my building at Texoma now...new owner has had great luck with it.

Half of them were from you

That's called a "C" swap.It swaps 4-7 and 3-2. It is what the LS engines use. Even though the cylinders are numbered differently, the firing order works out to be the same as a Ford.

That is the oil cooler on the bottom and a thermostat on top. The cooler is the original 525 cooler. It's a 2"x15" bundle, and yes it's to small. I will put a 3"x 25" cooler on it.
THe other thing to keep in mind is cooling. There was mention of the engine and headers getting hot. That doesn't surprise me at all. Everyone seemed surprised that they had 30 psi of water pressure, but everything was still running hot. A 2" diameter cooler has approx. (30) 1/4" tubes in it. The water runs through the tubes and oil goes around them. A 3" cooler has approx. 75 tubes. That's a huge difference in the ability to move water. A 3" cooler has almost 3 times the number or tubes, so obviously it can move quite a bit more water. They were reading water pressure on the inlet side of the cooler. That is just before the biggest restriction in the whole system. That would make the pressure high there, but probably pretty low in the engine block. It was mentioned that it needs a 2 stage water pump. In this case, it wouldn't have help a bit.
Little stuff like this adds up quickly. It doesn't take many items like that to hurt a 1000 hp engine. There isn't much room for error. Again, I don't know who is responsible for the above, nor do I care. My job is to find the flaws and fix them.

Soooooo....I was minding my own business reading that 2007 thread....and then noticed that I had posted on there...LOL. Wow how time flies when you are spending 50k a year on new motors. It was shortly after that thread that the engines started their yearly grenading....Im so glad that I have had such good luck since then...and been associated with such quality minded professionals....or not.
