I know they respond very well to mods and I know how they've changed over the last few years of their lives to improve the hp. But the majority of people dyno around 290-310 completely stock. I know you always have the exceptions, I just don't want to see those numbers get out of hand like it was an import throwin on some stickers or something

 

Believe me man, I thought the same way until I saw my friend's completely stock 2001 SS dyno 326 completely stock, and my friend's 98 LS1 auto with 130,000 miles on it dynoed 301 hp... pretty impressive.
