I am rebuilding a double overhead V-6 engine and have noticed wear on the bucket cam followers and would like to know if anyone has had a good result with DLC coatings applied to the cams and or followers?
What should be the Rockwell hardness of shim under cam bucket tappets on an overhead valve engine. I had mine checked and they went from the Rockwell C scale at 40 to 50.
I am restoring a 1974 Lancia Stratos factory race engine based on a Ferrari V6 engine. This engine has 4 valves/cylinder and 4 overhead cams. Displacement 2470cc with 10.5 compression. Horsepower around 300 at 8,700 RPM.
My question is this, the original cams the intake opened at 38 degrees...
