Needs more...
Sadly no matter what the actual Z06 factory stock HP may be it still needs more. "405" will be many Mustang's, 911's and rice burner's bitch. Step-up and add some boost to make the Z06 perform as well as it should.

Far fewer cars match the power to weight, power under the curve, available traction and balance to match the C5Z. 13 years later and the C5Z is still formidable in stock form and hard to beat in bang-for-buck.

Don't forget the aerodynamics, and close gear ratios. These cars are no mustangs or ricers bitch when driven properly. (13-14 GT500s) are the only exception.

tires are always the limiting factor. if you want something that wears well we still don't have tire tech that will really plant more than 360-400whp unless the car is AWD
you can go softer, or, you can use electronics but automotive performance has been limited by street tires for quite some time
i just can't stand burn out machines on the street. they aren't fast unless you're one of those people that measures everything in straight lines, they are difficult to drive at the limit and generally get crappy mpg
it's like you come into a corner, nail a great line coming out of the apex, then, you can't use the gas pedal until the car is fully straight or you'll just spin it around from having so much power on tap.

I don't buy the underrated stuff. Stock LS6 dynos are around 25-30 rwhp lower on average than your average LS3 dyno. (say 350-360 rwhp vs 380-390 rwhp). That difference for 405 vs 430-436 crank HP seems right on, and those LS3s are SAE certified for their rating, they should be spot on.
No real room for the LS6 to be significantly underrated, discounting dyno and individual engine variances since we're talking averages...

@ 12% drive train loss that puts you spot on 405HP. I'd say you're pretty darn close to what GM claimed. Unless someone has better numbers on drive train loss for the C5 Z06... I always estimated 13%, but I may start going with 12% from your dyno numbers Toque.

Imagine what would happen if some car's did not dyno what they should ?
GM would be SMART to make them a little more powerful than the badge on the side.
I always read its 15% for a manual.

My buddy just sold a 2002 911 Turbo with the X50 package rated at 450hp and I have driven several late model Mustangs. My buddy's 911 would pull me on the highway but would be a close 1/4 mile race. Only the GT500's with aftermarket pullies (pre 2013) will beat a C5Z. These cars are the best bang for the buck n/a'd cars out there IMO.
