Im having a hard time searching because of how general the terms are. But if all goes to plan, I may end up giving my build another go, and getting it broken in this weekend.

I know to keep the RPM's between 2-3 grand to allow the lifters and cam to seat to each other. Should I adjust where the RPM's are during the break in around the 2-3k range? How long should I do it? 20 minutes? 30? Does it matter?

I also have a bottle of Comp's Beak In Additive in some normal motor oil. Comp's additive I'm thinking will negate the need to add GM's EOS. I'm thinking they're pretty much the same thing.

And beyond that.... I have no idea really what all needs to be done.

Is it just a matter of checking for leaks and watching the oil pressure? What should I expect as far as coolant temperatures go? What's acceptable and what isnt?

I'm honestly scared to death that I'm going to screw something up or toast a cam or something. Just wanting to make sure I've got everything covered...

I would be wary of the 5000 rpm ring break in. That seems like it is for a race engine that does not have the time to wait. The rings will break in, it will just take a little longer and maybe use a little more oil during the break in. My experience has been if you don't have to rush the break in, then don't. Work your way up to the way you will be using the engine. Cost me $900 because of hot ******* (wot 6000 rpm) at 900 miles (2 scuffed pistons and a lot of slap) on my HD.

 

Im not so concerned about that part of it as I am the cam.

 

One thing that I do when starting the very first time, is let the engine start to heat up, 5-7 min. Then shut down and let it get dead cold. This allows things that are tight to heat up, expand, then cool, and loosen.

As for the cam, if it is going to wipe out, it will do so in during the first few mins.
