LS7 street motor in the 500rwhp club Had my 427 dyno tuned this past week by Nick Williams in Mooresville, NC. I want to say thanks to Nick and his crew for a job well done!
On the fifth pull it made 508rwhp and 462 ft lbs of torque. It has a ton of power under the curve. Based on 20% driveline loss or theoretical 1.49 hp per cu/in the motor made 635 hp at the crank. I left some hp on the table with the stock LS7 intake and the motor had very little breakin. Also, I think the plugs heat range was a little too hot.
All and all I'm pleased with drivability and it's a blast to drive. It can light the tires up at anything under 60 mph!

Is that a stick or automatic?
A stick will not lose that much and an automatic will probably lose more to the wheels unless you have a purpose built trans. the factory autos are more like 28%-34%
