The LT1 V-8 found in the latest 2014 Chevrolet Corvette Stingray is the most advanced engine ever put under the hood of a 'Vette--but how do its power and torque numbers stack up?

You could read the official spec sheets of course. Chevy claims 460 horsepower and 465 pounds-feet of torque from the new car, when fitted with the optional performance exhaust included in the Z51 package--the standard car drops a 5 from each of those numbers--but the only way to know for sure is to strap it to a dyno and generate some figures.

Edmunds has done just that with the Stingray, to grab the first set of real-world numbers for the Corvette. The outcome was impressive, even considering the typical drivetrain losses between flywheel and driven wheels. At its maximum, the 'Vette punched out 411 horses at just under 6,000 rpm. The LT1's torque is perhaps even more healthy, with a maximum 407 lb-ft just before 5,000 rpm, but no less than 350 pound-feet all the way from 2,000-6,000 rpm.

Both power and torque take a kick upwards at 3,800 rpm, as exhaust bypass valves open to unleash the V-8's full aural potential. The testers noted that such a step isn't normally seen on GM's V-8s, but reasoned few would complain given the engine's overall strength. For comparison, they lined its numbers against those of the 2010 Camaro SS's LS3 V-8, demonstrating the Stingray's extra strength across the entire rev range.

And if the LT1 is as tunable as previous LS-series V-8's, there's plenty more to come from the new Stingray...
