cam break in

ive just installed a eldelbrock performer cam into a freshly rebuilt (bored over with new rings / pistons, turned crank and bearings, and cam and lifters) the sheet that came with the cam says to run the engine at 2000-2500RPM for the first 30mins, any one else think them rpms are alittle high for that amount of time?

I recently broke in a Lunati VooDoo hydraulic cam and let it run at 1,800-2,000 for 20 minutes. I would say that 2,000-2,500 is too high.

I would HIGHLY recomend that you use Rotella 15-40 oil for your cam break in. Cams need zinc during break in, and Rotella is one of the few oils that still has it.

I have always done break-in at 2000-2500 rpms changing the rpms every couple of minutes.

Don't forget to keep an eye on the engine temp. If you start to get overly hot kill it and wait until it cools off before continuing the break in.

I called Lunati tech support for my new cam and they said 8 quarts of Shell Rotella 15W-40 at 2500-3000 RPM for a half hour. I've yet to do it (Sunday is the big day), but I'll let everyone know what happens.
