I also decided to try the aluminum blocked LS2, which saves 100lbs over the 6.0 iron truck block. I know the iron is a little stronger, but at my power levels, the aluminum should still be just fine. If I ever go boosted, it'll get swapped out to iron. I will also concede that a lot of the weight I saved, could have also been shaved off a big block by switching to headers and an aluminum intake. My goal was to build a motor that was roughly equivalent to a hp500 in power and weighed a lot less.. I'm pretty sure fully dressed, I am still 250-350lbs lighter than a fully dressed hp500, and am making slightly more power. But my main reason for doing the swap, was simply to be different!!
How is the boat doing so far? I really hope to run into you one day on Cumberland and check it out in person.

Been fighting reversion issues, so I had to dry up the exhaust. Heading down this weekend to re-install the headers. Hoping to be on the water Friday!!!
