what kind of oil for new rebuild

No disrespect inteneded to anyone, but you have to admit there are alot of myths and misinformation floating around WRT this stuff. Motor oil seems to have it's fair share. I don't know if anyone saw this thread from my post yesterday, but if you really want to begin to understand what's going on with oil these days, have a look:

I agree with using conventional for break in on these type V8s, and older engines. But only because it is cheaper and you are draining it after 500 or 1000 miles anyway. Newer designs are built to closer tolerances with different metallurgy, roller valvetrains, etc. etc. It really depends on exctly what we are talking about. Few blanket statements I have ever heard turned out to be universally true.

As was said before, cam break in is another issue entirely. I'm not claimimg to know much about engine break in techniques, but I do know some of the information bandied about concerning the synthetic myths is just wrong.

As always, YMMV.
