Chris, if you are thinking about a SC, think well past the SC kit and pistons. Think pistons, rings, rods, main studs, head studs, gaskets, fuel pump, fuel injectors, SC kit, machine work, etc etc. And while you are there, it might as well be a stroker, get some head work, etc etc 
All so you can fry the clutch and pop the 10 bolt :tup: The rebuild is a given if you want to go FI.
Ive had a blower and bottle for my LT1 and blower for my LS1, so if you have any Qs, let me know. Easier to explain everything you will run into in person.
