Good luck with the install. Please post the results.

those are definately impressive dyno numbers for such a mild cam. comparing similar cams from the GTO board most guys make around 425-430 on an ls2 M6. I have seen one guy recently put an HPE S2 cam in with a fast and made 460 on the stock heads, so sure 450+ is possible cam only. i was just saying the normal (from my experience) is around the 430 mark. like i origionaly said it comes down to the power goals and putting together a package that suits that particular drivers needs. if someone were looking for 500+ WHP and planned on going 408+CI id always choose L92's over ported LS6 style heads, if someone with a stock cube LS2 were looking for lets say 450-490 i'd say you could get there alot cheaper with just ported 243's. i get what your saying about not needing a large cam, but the origional question was L92's over ported 243's. i was just averaging power numbers that i had seen on the GTO boards to make my point.
I'll definately post my results as soon as i get the car on a dyno, though i'll most likely have a timeslip way before i have a dyno graph
