And what does the high overlap lift when the engine is cold?

Did you even make the camshaft yourself? Cool!

Would you mind if I put all these posts into one topic? I think it woul be appropriate to have them all together.

Edit: question unclear after the merging of multiple topics

Did you manufacture them the rods yourself, or is this a reproduction?

I notice that the FCStd model is in one part, while the real-life rods are in two parts. I suppose that the lost thickness due to the cutting process does not matter? (I know nothing about engines)
