Still waiting on the rest of the kit. Got the cam and timing set so I threw most of the engine together.
Here is a pic of the LS3 coolant crossover that I am running in the rear along with the DPE corvettes 2.5 bar map and the map sending unit for my boost gauge.

The most popular theory about toasting the #7 cylinder is lack of cooling in the back of the engine due to the 99+ engines having the block off instead of a crossover. I decided that was a logical theory. So instead of buying one of those expensive crossover kits that links all four corners of the heads together I went with the cheaper option of another crossover.
It may not be necessary, but I don't want to really take chances with all the jack I'm spending on this build.

I know about the crossovers. Just was wondering if their was something about the ls3 style.
I used a 98 crossover on mine. But I still need to route it back in to the cooling system. Right now its caped.

I figured if it was actually a hose that it would give it a little more versatility. Turns out it fits just fine back there without being in the way.
