Oil weight
Just wondered what oil you guys run ? When we built our motor we ran break in oil. Then i did a few oil changes with regular ole motorcraft 5W30 but I think I'm going to switch now. I was thinking about 10W30. Thoughts ?

Amsoil Dominator 15w-50. Heavier oil protects better.
Factory oil weight is based on mileage standards, so they move to the light side. If you plan on flogging an engine I wouldn't run anything less than a 40wt.

Not exactly true, it provides more cusion, but it also can't fit fit into smaller clearances. If it can't fit into them, they don't have any protection. That's why we don't run gear oil in our engines lol
I was told previous owners run 10w40 in my engine, so that's what I use.
