Thank you very much for the info and pics. Understanding how the craziest oiling system ever designed by man has been made much easier thanks to you. Isn't This the same setup used in WW2 Chevy trucks? I have a question. Doesn't it take a bigger oil pump to keep those jets spraying like in the vidieo? It's wonderful to see real craftsmanship in action. Has the head been put on yet? Jay 6155
