The BD3 are a proprietary (sp) grind
and Crane will not give you the specs. However, if I
remember correctly the gross lift was .340" (yes .015 less
than stock) and a gross duration of around 290 (I am
sure on the lift but not the duration).

Bill
Hutton should have the spec's, he had them
made.

Since the Cams were a custom design by Bill Hutton you will have to
ask him Crane WILL NOT give out the information because it is a
Propritory Grind (owned by Hutton).

From memory the last was .007" - .008" intake, .009" - .010"
exhaust, gross lift was .340" (yes it's a lower lift than the stock
cams) and I can't remember the duration.
