a 615hp 427 ls3 that comes with absolutely everything including a full tune, VVT computer and a valid warranty costs 13k. a 505hp ls7 is much more money just for the engine.. and when you add cam, harness, computer, dynotime dry sump tanks and hoses and gaskets etc. you are well into the 17 grand range, if not more... thats 4000 dollars wasted on the ls-7 name (and a voided GM warranty)... stupid in my book...

I assume you are talking about the Mast Motorsports ls3 here. I haven't seen the graphs's supporting their 615 hp claims while retaining the VVT, I am not saying they are not true, but I haven't seen any evidence supporting the claims.
FWIW, the ultimate N/A power potential of a ls7 427 is much higher than a ls3 based 427.
