    Hardened main bearings or not?

    Are hardened mains the way to go or better to keep them standard for 700+ hp?

    Anyone used them?

      Didn't think mains were. I knew rod bearings are.

        Aby / rs2 were hardened standard over coupe / 3b
        Think aby/rs2 are standard now

          Whatever you go for make sure it's sputter. Glyco are popular.
