What synthetic weight should I use for the 420 oil, transmission, and the finals?

I run any synthetic DIESEL oil. They have a higher zinc content and Help with flat tappet cams.

If you rebuild any flat tappet cam, make sure the oil you break it in with has the zinc so the cam won't wear out too fast.

Oil is cheap, engine parts aren't
