It will list the rating from the factory at the crank. However the numbers will vary greatly since a dyno pulls the numbers at the wheel.
If I had to guess I'd guess the gen 1 series one l67s are 170ish.
gen 2 or 3 whatever are probably in the 180 something range
sheer guess, but I'm not aware of anyone who has dynoed a stock series 1
