What are your plans for the car? N/A? Spray? Boost? Need a little more info.

but more than likely.. 418.. can't go wrong with more cubes.

I would have to agree the 418 ls3 is a very versatile platform. I would use it n/a, boost, or nitrous.

Eventually spray. But for awhile its gonna be N/A. What about a cam? Should I go with a custom grind or order something like the Texas Giant or something along those lines?

Custom cam hands down. Set it up for nitrous from the start cam/rings/crank rods.
