That cam doesnt make peak power till ~6400-6500rpm... he needs to get it there to see what power it makes. I agree, he needs to be sure its pulling clean (which a dyno graph would show us), but in the end he needs to get the revs to where it should be for that cam in order to get good numbers.
BTW, on my 383rwhp run with my XE230/236 (that made peak power at 6000rpm), I was only at 340rwhp by 5100rpm. I dont doubt that he should see 400rwhp if he can get a clean pull up to 6500rpm.

My point is, everyone thinks he should be 400rwhp+... show me a N/A LT1 that makes 400rwhp @ 5100rpm. Never going to happen.

you cant have a winner without a graph, how do you know the power did not drop off after 5100 and they did not rev it out, you dont know that. i can only imagine his tuner was smart enough to rev it out past 5100 but did not get results, indicating a problem not related to how far they pulled

I'm still a winner in my book

Hell my stock bottom end car is at 370-380rwhp at 5100.

Spin the car to where the cam wants to go and scan up a graph, then we can talk.
Without enough info to go buy there is nothing to do but "guess".
Also, remember that most "real world" dyno numbers tend to be quite a bit lower then "internet" #s
