Oil for a street/strip engine?

[Johnny]

I would contact Dave at Red Line Oil Company.

If I were having that engine built, I would start it out on the Red Line 10W-40 with a bottle of the Red Line Oil Break-In Additive and follow Dave's instructions.

Just my humble opinion from past experiences.

Don't forget Amsoil Dominator.

We run it in two dedicated race platforms and it is great.

Run the lightest grade that doesn't burn off.

Full of all the good stuff.
