Ordered Royal Purple break-in oil and Lucas hot-rod and classic car oil. All 10W-30. Both are real high in all the right ingredients.
So... how should I break her in once I get the new cam installed?
I took some tape and marked where the distributor was positioned before removing it. I can set it pretty close to correct before even starting it now. I'll use assembly lube on the cam and lifters and then prime the engine with a drill. To do the valve lash adjustment I figured I'd leave the valve cover loose for start-up and can adjust them as soon as I start the engine. I'll get the valves snug but not tight to start. Then, while it's running, tighten them up slightly. I don't want to go too tight during break-in so I'll just snug them until the rattle goes away and no more.
How long do I run her with the break-in oil? I know for break in I don't want to keep it the same RPM and I don't want to push the engine hard.
Never broke in an old engine before. New ones are a bit easier.
