Low numbers??
I recently dynoed my setup and it made 456 to the rear wheels. I feel that this is a bit low, but maybe not. It was on a mustang dyno. I don't have the graph with me. My setup is a LQ4 block bored .030 over, callies compstar rotating assembly, Wiseco -7cc pistons, slightly massaged LS3 heads, L92 truck intake, LSR 236/248 615/618 110+4 comp cam, all thru a circle D 3500 single billet disk converter and 4L80E stuffed in an 03 RCSB 2wd silverado. What are your thoughts and what would be your guesses for the power range? Also would it be possible to swap heads out to achieve 500+ rwhp and still be streetable?

The numbers sound pretty fair. It looks like a pretty nice combo you have there. Getting to 500hp is no easy task without a power adder or some extra cubes. Although you have a bigger engine and thus more to work with, only a handful of guys over on LS1tech have achieved the 500hp goal N/A with the 347 engines on pump gas.
You do have the displacement advantage though, and a good set of heads and tuning would probably be the key. Compression ratio will need to be high. As far as streetability goes, I'm not too sure, though a 3500 stall doesn't sound too streetable to begin with.

what is your compression? i run right at 12:0 on pump gas, do i daily drive it no? why? cause no AC. would i if i had AC you bet your *** i would, but not anymore cause of bars hanging out the back glass lol, though i run a big bump stick 252/263 and a 4500 stall, a great tuner can tune the truck to daily very well 
Quik came down and we dynoed the truck before the SAR shootout, dyno we used sucked big time ops didnt know how to set it up nor how to use it, i can probably say the dyno probably wasnt even calibrated, alot of people after the fact told me there results were crap on the same dyno <-- who cares its a dyno and my times speak for themselves, 1.42 60 fts back to back and 11:00 pass was good enough for now, so a 511-21 rwhp wasnt to bad but i know it can put down more, but since the 60E is done a TH400 is going in with trans brake, this should net me the times i been looking for NA 10.6
sorry got alittle carried away with my setup lol but besides the point you have a nice platform, so are the numbers low? hmmm not all setups are the same, swap heads? you have the best stock heads that are on the market lol just have to match everything up, what exhaust you running? collector size? primary size? youll have alot of drivetrain lost for what you have now.
Beatdown asked some important questions, the CAI what size is it ? i wouldnt go nothing less than a 4" tube, i run 2 of them or i could run 1 5" tube. i run 101 Kpa WOT now that i have the Holley High Ram she sees 102!
id really like to see your dyno sheet ? what was the torque, im sure it was up there probably around 4700 or so

When I get back to the house I'll try and remember to post up the dyno sheet. I ran it at Thunder Valley this weekend with a set of 28x10R17 slicks on a set of gmc aluminum alloy wheels. My best pass was a 13.5 I don't think something is right with the tune, the truck feels like it's lost a lot of power. I'm running a big K&N filter right off the TB(I know it needs to be changed. My exhaust is cal speed 1 7/8 headers with 3" collector and 3.5 Y pipe into a stock '13 6.2 muffler. As far as the rest, kpa, intake temps, and whatever else I'm not sure. I am still learning the tuning side of things so I'm looking for someone who is better knowledgeable to help tune my truck. Any advice will be taken and appreciated.
