I was just thinking....
Skeet's LQ9 based engine did 480 rwhp IIRC. LQ9 short block, ported LS3 heads, 23x/23x @ .050" cam, all the supporting mods... headers, injectors, TB, etc.
Post #3 he lists mods, weight, etc.

Correct, 9.3:1 vs. 10:1 SCR. Most likely wouldn't notice more than a 10 HP difference - at the crankshaft.
You are looking for 450 rwhp, Skeet's set up could easily be duplicated and make 450+ with similar parts.
Just food for thought...

A new and better set of lifters are cheap insurance at this stage of the game. Should do a cam now, much easier now than later.
Me personally, would do cam, heads, intake now. Just cam it for a supercharger, then add one later. I always think I have "enough", then I get bored.

Update: engine is all torn down list at the moment is new oil pump header exhaust supercharger cam. My concern is have it this far down should I just put high flow l92 heads and intake on it but I have no idea how to hook up the l92 intake that has no gas return line but my truck does and if everything els like sensor wires would hock up still?
