need cam advice from 351 guys

[Rev]

There is some leeway in the way manufactuors measure "advertized duration". I think the best way is to compare duration at .050" lift. Sometimes, advertized duration is manipulated to give higher numbers because that seems to be what some people want. What some manufacturers do is to start the ramp earlier and end it later, but at miniscule amounts to artificially raise the "duration".

The 224/234 @ .050" numbers tell me this is exactly what Crane did. As a comparison, my 268 HE from Comp Cams is 218/218 @ .050". So I'll bet your still OK if a max street cam is what you're after. It might compare to another cam advertized as 280/290 or something like that.
