i installed my new clifford cam in my 292 it is the mild 264 grind ( i don't know that much about cam theory). i spoke with them on the phone and they said 1100 rpm's for 10 mins would be a good break in. i did 2000 rpm's for 20 mins with my stock cam. i asked why the difference they said it was a hardened cam and the fewer rpm's for less would be ok. what does everyone else think? i want to do the best for it. the engine is all new and about a month from start up. thanks for input. not i don't trust their advice i just wondered what everyone else is doing.
