That should be 280 degrees at .050, .4468 lobe lift ground on 108 lobe sepperation angle on both lobes if I'm inturpreting (SP?) those numbers correctly

That's right Cab, just hoping for the rest of the install numbers. I ran one of these 20 years ago, and don't remember the details.

Deaks, don't think U highlited the right cam. Don't think I see it here. Cab's comments are right, 670 lift[1.5]. We installed it at 103.5 and set lash at .026 500" 440-1 motor. Great sounding cam, still have it.

Bill, What compression are you running and how's the e.t.? I'm going to use my old Stage VI's on mine...so it will be considerably slower.

New question on this old subject, I've been running this cam installed at 102* thinking of retarding it to 106*-110* any predictions on the result of this change?

Quote:Intake..duration 294duration@.050..lift .741 Exhaust..duration 281@ .050...lift .693 both with 1.5 rockers. 110 centerline no cam advance. Seems to run a little better with lash .010 tighter. Car is a tenth or two quicker but 60fts a little better. No change in MPH. Sounds nothing like the old Crane [best ever]. Running Comp 948 springs and will pull to 7600 now.
