Question, how are you porting the block for oil passages?
 That's  the one thing the guy that did the roules Royce airplane engine would not divulge.
Is a car in the planning?

I am not running a pressurized oil system. It will be a splash system like a Briggs Stratton. Once in a while the valve covers will need to be removed to lube the rocker arms. If you look at the bottom of the 4 pockets, there is a slot milled about .200 deep in the center of the pocket. When the cam tunnel is bored, those slots will break thru and oil will reach the cam and lifters.

No car planned. I will spend the better part of a year building this thing. I would hate to smash the thing up in less than an hour.

So how are going to grind / do the cam and crank?

I intend to do the crankshaft on the lathe from some 1 inch square bar. The cam will also be turned in the lathe in a fixture. I wrote an article on making camshafts in the lathe using a chart to keep track of when and when not to cut the lobes.

That answers my questions. Excellent and time consuming. Can't wait to see more pics.
The crank is easier than doing a cam. Just need a couple well placed center holes. I've made a couple larger ones for a punch press years ago.
Thanks for sharing ,  an excellent project.
