Here's another option for you:
http://cgi.ebay.com/ebaymotors/GM-L9...1%7C240%3A1318 The L98- LS2 with LS3 heads and accessories, harness and some other misc stuff. Swap in another cam and you could easily have 500 hp (crank) for less $ than the others.
I bought an L92 crate and am now try to decide whether or not I am going to keep the VVT or not. The one good thing about the mast stuff is the wiring and alot of the bugs are worked out for you. Just depends on how much power you want.
