A lot of the May 2014 issue of Vette magazine is dedicated to the C7. It includes drag strip, road-course and dyno numbers of a base (non-Z51) with automatic trans and NPP; SEMA coverage focusing on C7 products; Aftermarket tuners products; and a detailed article on the tech behind the new LT1 powerplant. An interesting tidbit from their dyno tests is that the base model pulled 410.88 hp and 419.71 lb-ft of torgue at the rear wheels on the first pull and virtually identical figures on follow-up pulls! They state based on that the yields "at the crank" to be 483 hp and 494 lb-ft "demonstrating GM isn't afraid to underrate the output of its flagship performer. While most of their comments (again just on the base non-Z51) were very positive they did not like its performance on the track as compared to its performance on the street and drag strip. Get yourself a copy if you don't already receive it. Lots of info.

When you're mass producing engines you'll get a variance in hp from one engine to the next.

Dyno to dyno result consistency is "not consistent." At the same time, their 483/494 readings are incredibly powerful!

That's true also dyno's are another factor to inconsistent results.
