Default Horsepower estimate please

I have been working my 99 Z28 for a few weeks, At first I just wanted to do heads and a cam but it has evolved into a total motor rebuild with lots of little bolt ons. The car is up and running and I soon plan to get it on a dyno, but am not sure what number I should be looking for.

Here is the full build information:
Motor has 70k miles
LS6 heads
LS6 Intake manifold
Lingenfelter (comp) cam, GT2-3 link to specs
SLP Long tubes
No cats
exhaust running to borlas the car had when I bought it.
Ported and polished throttle body
Under drive pulley
SLP high flow lid

So far I am very happy with the way the car is running, just looking for some number estimates to I can tell if car is really running right or not.

Get it on a dyno, and get it tuned. A tune should be considered mandatory once cams are swapped, and with heads/cam it will really need it.

Also remember that dyno numbers themselves are not very important.

What do you think the RWHP is on a stock Z06? This guys has more cam, even if it is small, ported throttle body, SLP MAFS, SLP Lid, long tubes with ORY and underdrive, plus all of the Z06 parts. Just curious of your basis for the "lucky 360"
