Cam wiped out, what the hell did I do wrong?!?!?

Stroke motors do like lots of cam, however many say its better to error on the smaller size. This cam here in a 360 would be a hot street profile. Check out the lift, like .550 and its a hyd roller cam by

Looks good, but I was always told that on small block Mopars, you want more lift on the exhaust. Maybe the extra duration on the exhaust would make up for it. Looks similar to one of the Comp cam profiles I was looking at earlier, but it was on either a 108* or 110* LSA. I haven't even checked out Crower yet.
