I finally was able to obtain all the parts for my WL/KH engine build, got the mockup engine out of the frame. Tore it all down, inorder to begin working on the assembly.

BUT, what I thought I had in the past bought ... well turns out I did not. and my memory was not as I had hoped.

OK, here is the gist of the issue:

Does three hole crank pins offer a vast improvment over the 2 hole ones?

I thought that I had three hole crank pin, but I don't.

For better bottom end oiling/long life should I get a 3 hole crank pin, to replace the 2 hole one that I have?

OR just go with the 2 hole one I have.

I prefer the 2-hole pin. Plenty of oil volumn and the oiling holes are not in the bearing path.

Thank you for your honest input.

I will go with what I have already bought.
