rebuilt engine

[rangerkh]

had my 360 rebuilt - been sitting for a few weeks and forgot what type of oil should I use for the break in after I get it installed? On a side note I have a few left over parts from the engine that donated the crank and block. I have the heads and oil pan and valve covers from that engine. do the heads have any value or should I turn them in for a core charge or does someone want to buy them?

Thanks

The heads have some value, just not a lot. How much core value would they have for you?

The oilpan would be useful for us rust-belters; they tend to corrode and develop pinhole leaks.

As for break-in, I just used 10W-30, then drained it and put in fresh oil after the first 30-minute run-in. Then I change the oil after the first 500 miles, then ever 3,000 afterwards.

An engine builder I've talked with in the past tells all of his clients to run straight 30W for the first 500 miles, then drain and replace with 10W-30. I have no experience with this, but thought I'd pass it along.

I built a lot of engines when I was in the auto business. My recommendation has always been 30 or 40 weight non-detergent oil. Change 200-300 miles to detergent type 30w or 40w depending on ambient temp.or multi-viscosity if you drive from one extreme to another. Change every 3000mi thereafter. I recommend valvoline, then castrol in order of preference. I never liked pennzoil. I could always tell when a client used pennz. by all the excessive black , waxy sludge in the block and on the rocker arms. They would always say: " How did you know?"
