My first iron OHV casting!
Here is the first iron OHV casting. Still needs cleaned up and final shot blasting. I think it came out very nice for the fist one.

Re: My first iron OHV casting!
From someone that doesn't know what they are looking at, I think that looks very nice. Where would the spark plug be located in such a head?

Re: My first iron OHV casting!
It looks like both the exhaust and the intake valves are in the head. Is the head based on an existing design or is it a new design?

Re: My first iron OHV casting!
I'm curious about the valve stem casting, does having it extend so close to the valve choke the air flow or is it a benefit, on the intake side at least?

It’s a copy of my original Scholfield 1930, which I loaned to him for copying. It was after Miller and before Cragar.

Re: My first iron OHV casting!
How about looking at putting a quench type combustion chamber in there also while your at it.

Re: My first iron OHV casting!
Yes, great copy. It will be exciting to see how your ports flow and see what comes next.

Re: My first iron OHV casting!
Tod, how do you establish the internal shapes of the water passages?

Re: My first iron OHV casting!
Tell us about the valve train, is it one you are making, or is it one you are adapting from another motor?
Where are the push rods coming from, made special for this engine or from another motor? On the spark plug question I assume those will be cut in after the casting, or can't we see them from the angle of the views?
