@ sea level sure they can run those times... but not at close to 4000 ft altitude 
but yes, i'm eager to run at mission... but I can't afford to fix the car if it breaks at the moment (wedding to save for, etc...) so i've been putting it off and off and off... but eventually i'll get out there!

I guess the only true measure is the good ol' dyno

I've never weighed my car nor have I ever got a 1/4 mile time - so I had to guess..........I think this may be fairly accurate.
Wow!
I thought it would come in around 6000HP!
I'm pretty happy with the results.
Horsepower Results - 1/4 Mile Method
Your Camaro Z28 weighs about 52904 pounds and can complete a 1/4 mile in about 11.03 seconds. That means that you've got about 7792.01 HP at the wheels, and about 10129.62 HP at the flywheel.

You can't go by the 1/4 mile ET since you have no traction etc.. MPH would tell a lil better. This one works better as you will see.
According to my cutlass CRATE engine which advertises at 345 wheel hp this is pretty bang on.
MPH of 110 with a car that weighs 3350 it shows a calculated hp of 348!!!

According to my Supra results I should have around 510 Wheel.
I dynoed that car at 450 before but gained almost 6 mph since the dyno so maybe it would be close to that.
New set-up now anyway!!

EDIT: Erik > yours shows you would be around 344 but hey. We have to do the timing and a few adjustments for next year anyhow
Low to mid 12's for you I hope for next year!

Dunno....
390 RWHP for my weight at 110mph trap speed
379 RWHP for my 12.50 ET.
Dunno I guess I will see when I get it on a dyno and tune it in a couple of weeks.
Times in sig I weighed 3650, calc says 413 RWHP for those figures
