I cant help ya on the hp deal but the cam dosent look right for some reason. The intensity looks to be off. afr heads have decent mid lift #s and that cam may not take advantage of them. You might want to look at something like comps 288HR and see how those #s look. maybe some others will chime in here and help out. Dave

Crane rates their cams at .004", the SAE standard. Other companies rate their cams at .006", or even higher, to give apparently shorter seat timings. This is one reason why the DCR doesn't always come out the way you think. And I am guilty of this, too. All my future designs will be rated at .006", except for the Chryslers, which will be .008"---The common height among Chrysler cam manufacturers.
