I know I want to do a LS conversion, and here's what I been debating about lately. Keep in mind these are Canadian prices.
Choice one is the GM 480hp LS3 crate engine. I can get it for about $6800 CDN. Engine is all aluminum and comes with car intake. Still would need to get a wiring kit for it.
Choice two is a L92 with cam and intake upgrade putting it to about 525hp. Will run about $7800 CDN. Engine I believe is all aluminum and has LS3 heads. Still would need to get a wiring kit for it.
Choice three is a Mast Motorsports LY6 with 480hp. Can get it with a car intake upgrade for about $8500 CDN. Engine has a cast block with LS3 heads. Comes with the Mast wiring controller which is apparently really easy to hook up. Engine is already broken in on the dyno.
Choice four...help me out if you think there's a better option for around the same pricing.
If you do make a selection or have an opinion, I would really appreciate it if you told me why you think I should go that route. I don't know much about LS engines at all so this is all a learning experience and any info would be greatly appreciated.

I've gone through a similar process and settled on the GMPP 376/480 with the GMPP wiring harness and the GMPP accessory kit w/o air. The harness is plug and play, comes complete with electronic throttle (aka gas pedal), MAF sensor, wide band O2 sensors, bungs, etc. and is programmed by GMPP for the LS3 with the hot cam installed. With respect to the other tuners out there, this is not GM's first time at the LS3 tuning party.
I also went with the GMPP accessory drive because it was cheap and engineered for daily use in the Corvette. Finally I got the Kwik Sanden AC compressor adapter kit for use with the Corvette accessories and I think I should be good to go. I may upgrade the accessories at some point in the future, but this car is already costing cubic dollars.
Oh, a 2 year warranty on the engine also isn't too shabby
assuming GM survives.
