There IS a break in period for ANY camshaft Sam.
Even Crane, CompCams, Elgin, and Crower will tell you this.
"IMPORTANT! Don't allow the engine to run
at less than 1500 RPM during the first halfhour
of operation. Slow engine speeds invite
premature cam and lifter wear and may
cause their ultimate failure. Change RPM
frequently to direct oil splash to different
areas of the camshaft. Vehicle may also
be driven during break-in period."
Even with used rollers, you still need to "break in" the camshaft.
Remember, they're coated with a special lube for initial break in.

There's really not a break in for a roller cam-- that procedure is for a
hydraulic cam (non roller)... But it wouldn't hurt.

Hi Bob,
Once you get it cranked up, run the rpm around 1800rpm for a good 20
minutes. I ran mine between 25-30 minutes on both cam break-ins. After
that, you should be good to go, but I did treat my semi-gently for a few
road miles until I felt comfortable with it. Have FUN!!! Rich - Ashburn,

Hi to all you cam swappers,
I'd like to know what method you used to break in a roller cam after the
install? Also, what, if any, precautions you took when driving after
the break in? I thank you for any real-life inputs.
Bob
