Ls3=366whp?
Can this be all? Was watching Dave Kindig's show and they were building a T/A with an LS3 drivetrain. Took it to the dyno shop and it turned just 324hp and after leaning it out it made just 366. I saw a large chrome intake tube on the motor but didn't hear of any mods. Damn, what's my LS2 have at the rear?

I've seen anywhere from 365 to 400 rwhp with C6 LS3s in stock trim. Autos will make a little on the lower side, manuals a little higher. NPP picks up a couple as well. Then you have all different brands of dynos and even with the same brand it can differ from one shop to another. There's also many different correction factors and levels of smoothing being used. Altitude and octane of the fuel can make a difference as well.
For what it's worth, my car made about 425 on just headers and an e85 tune.

Factor a ~15% drivetrain loss with a manual and thats right on the money. (430x.85=366)
324 sounds low unless its a auto with a big rear
On another note, are you still running e85 on the stock pump?
thanks,

Yes, since I did the conversion I only have ran gasoline one time as I couldn't get E85 on a road trip. The OEM pump keeps up fine at this power level. I have stock injectors out of some flex-fuel SUV and they are at 85% DC. Perfectly matched injectors built for ethanol (no iron to rust inside) for about $470 new.
