The machine shop is nearly done reconditioning my engine parts. I will be installing a new camshaft and will need to do a proper breakin on it upon first startup.

What is considered the proper RPM for breaking in a cam on a 1958 Chevy 261?

I never liked the idea or reving a new engine too much. I'm actually quite nervious about this.

Thanks inadvance
