Doesn't talk about testing conditions but that will point u in the right direction. I would say just look up the new standard code and some details should be available.

Ultra is dead on with this. Go pay to have your car dyno'd at ten different chasis dyno shops and you get 10 wildly different results. Have you engine removed and dynod on 10 engine dynos and you get almost identical readings as long as the air is controlled (temp, pressure, humidity).

Extrapolating real engine numbers from chasis dynos used to be the only way to see truly if manufactures were under rating but even then those estimates were just as inaccurate as they are now. The only accurate ratign system in the US are SAE certified numbers. This why high end shop that develop cams use engine dynos for testing and developing.

Back to the topic...
LT1 C7 (3300lbs) - 0-60 = 3.8. 1/4 =12.0
LT1 Camaro (3700lbs) - 0-60 = 4.1 1/4 =12.4
All of the magazines I've seen show the 1LE faster than the SS in 0-60 times because of gearing and sticky tires. So the SS could range 3.9-4.2 depending on gearing and tire options.
