I'd be curious to know what the modifications were made after 2000 to increase it by 30rwhp. Generally, there is closer to 17-18% loss on new manual transmissions.

There is a new artform out there. It's called BS dyno pulling. A lot of the new dyno's allow you to enter parameters which skew the output, and a lot of shops are more than eager to show inflated numbers because everybody wants to see their car pulling serious power. I feel this is the sole reason for the mystical increase of 40hp.

The LS1 isn't notably faster now than it was. An increase of 30rwhp would make most of them borderline 12 cars at more like 109-110mph traps. I haven't heard of that trend.

I can say the LS1's valvetrain is weak, and contrary to what I'm being told, I don't believe it's gonna last past 100k. 10.5:1 compression is HELL on piston rings.
