Do you need to do a break in with new lifters on a used cam?
2000-2500 rpm for 15-20 minutes?

It is not just conventional... it is true. Had friend put a new cam in without new lifters before he know.... lasted about 20-30 miles. Hard way to learn.The way I always understood it was
New cam, New lifters
Old cam, New lifters
but never New cam, Old lifters.
Is this still the conventional thinking?
Back in my dealer shop days we installed hundreds of new lifters on old cams under warranty... never had to worry about a break-in time because those stock springs didn't have much pressure and the customer would never pay attention anyway.
I remember when the dealers always told a new car customer never to drive over 60 mph for the first 100 miles... old school way of breaking in a new car. That didn't take into account the new car set-up guy (me!) going 120 mph on the 'test drive'! I broke in hundreds of Hemi's, 383's, 340's, six-packs, etc that way...
