Not too suprising- stock GTO's are getting in the 330's at the wheels. They seem to be tuned down from Vetts in spite of the fact the weight difference should be enough to keep them from running close together.

Heads can be changed, you know.

all ls v8's don't have 7 liter and heads that flow 384cfm

Nah, this is at Coastal Dyno. Sam and company build some badassed cars.

Where in FL this isnt Lamottas Performance is it ?

This was all on a factory tune, factory air-filter, factory exhaust, factory air in the tires, factory everything. Box stock, as delivered by Chevrolet. 7000 miles on the clock and one oil change.

Down here in FL, those seem to be average numbers for what everyone else is getting.

Now the car has the SLP Loudmouth I exhaust, 160 degree thermostat, a Blackwing air filter and the SLP tuned PCM is sitting on my desk right next to me. When I video the "after" dyno at the same place, I'll make sure to run up to the computer screen and get the results so there is no doubt as to what the car did.

All right two last questions. Is this on the factory tune and what correct factor was used? Not to be a jerk but I think you can even admit these are extremely high numbers for a stock LS2. If it was been tuned I'd check the A/F ration because it might be running in the danger zone way to lean. I do agree on your comment about the LS2 being a better choice than the LS7 in most cases. All it takes is a full exhaust and a mild cam and it will easily put down better numbers than the 7.0. Plus you could can buy two cammed LS2's for the price of an LS7. If those are your the correct numbers total stock than you got one factory freak of a vette.

Did it sound modified? I assure you, the car was as stock as stock can be save for an oil change 2k miles ago.

Oh well, you can read about it in the magazines soon. :)

I still don't know if the car is stock and also who knows if all the info was put into the dyno correctly. I'm sure you car has plenty of balls but I guarantee those numbers are off.

I've got the dyno sheet right here.
