Sam:
On a brand new install with cam/lifters (and using the break-in lube
that comes with most of the hyd/roller kits) yes...there is some
break-in (about 10 minutes). If you're just changing the cam without
changing the lifters, then there really isn't a break-in period.
However, run it for a about 5 minutes, vary the rpm's up and down, make
sure you've got oil pressure, shut it down, change the oil, be done with
it.
On the procedure...my bad, I posted the wrong one.

OH okay... Bernd must be right.
Crower must be wrong.
When I walk into Crower tomorrow and sit down with David Crower to
discuss cam profiles, I'll let him know that he is wrong in telling ME
there's not a regimental break-in for my roller cam, only to just
install it-- and drive the truck normally (and of course making sure
everything is A-OK before I romp the living piss out it like I do).
Just like adding new roller lifters, or roller rockers...a roller cam is
no different (general common sense is to take it easy, let things seat--
50 miles or so, varied driving, no WOT max rpm runs).
The procedure you listed is for a hydraulic or solid lifter cam. Plain
and
simple-- I did this last year, 2000 rpm for 20 minutes on my 383-- with
a Crower hydraulic cam, non-roller.
