The most RWHP from an LS6 w/ just bolt-ons?
Here's the thing...I put down 335/345 on a Mustang dyno with my stock '00 ls1 (305 HP) with just the bolt-ons in my sig (I did it with the LS1 intake, too). I'm putting in an 04 LS6 advertised at 405 HP, so what will it max out at, do you think, with just bolt-ons? What's the max any of you have gotten with an '02+ LS6 and just bolt-ons.
...I figure it'll be at least 24k warranty miles before I start thinking about upgrading the cam and swapping out the LS6 intake.

ditch the cats, do a cut out, FM merge, ditch the LM for at least a 3.5" exhaust, 4" if u ever go cam/heads, udp, FTP 98mm lid, 85mm MAF, 85mm tb, typhoon mani with fuel rails(maybe injectors too).

Thanks for the suggestions; I'm definitely headed for a full tune as soon as the engine is installed. Already running an 85mm MAF, but will wait another 24k miles before swapping the LS6 intake and cam for something bigger.
Underdrive is on the list; gotta keep the cats for ODB2; thinking of doing true duals with the TSP X-Pipe & LM 1's
But, what i was trying to get at, is how much RWHP do you think we can make with an LS6 and just bolt-ons? At first I didn't think I could even get close to 400 RWHP, but after I thought about getting 335 out of the 305 HP LS1 (with a few missing pieces), it seems like it might be possible, and I was hoping some guys could share what they've seen out of a stock internals LS6.

My LS6 CTSV did 402rwhp/387rwtq on a dynojet with bolt ons.
Mods were:
Ram air intake
FAST 90
Electric waterpump
Kooks LTs
Mangaflow x-pipe
Flowmaster super 44s
aluminum flywheel
dynotune
Obvisouly I have some things that you don't, but an underdrive pulley would probably show more gain than my EWP did and your solid axle car has less drivetrain loss then my IRS so the flywheel difference would probably cancel out as well. And I don't know how much the FAST will hold you back on a bolt on car, but it probably wouldn't be much.

I always wondered how much the EWP was worth. Looks like pulley and x-pipe are next. I'm going to resurface the flywheel while the engine is pulled; there's 50k on it and the clutch plate, but I'm not sure the the aluminum flywheel is worth the bucks.
BTW - the McLeod clutch has been awesome for uncounted 4500 rpm launches

That's what I'm talking about...thanks for the feedback.

And yeah the codes can just be turned off. I just had my WS6 inspected and it doesn't have one single O2 sensor plugged up, no MAF, no EVAP, no AIR pump and passed the OBD2 scan just fine.
