6.0 with LS3 engine combination

[Dan Shook]

I am considering building a LQ4 and installing LS3/L92 heads, LS3 intake and TBI with a cam, possibly the gm hot cam and springs with headers. I have a few questions, first off what kind of horsepower numbers are realistic with this combination? With this combination of parts is it going to be a major issue to get a wiring harness and pcm to make this combination to work in a very reliable fashion? Does it make sense to go the route of running a carb to simplify the wiring needed to make the fuel injection work? My other concern is am I going to be close enough cost wise to consider going with the gm crate LS3 engine and harness. Any input would be greatly appreciated. Thanks
