VCCA Home Forums TECHNICAL - 1945 AND EARLIER Chevrolet Speedsters '28 2 port motor speed equipment

What speed equipment was available for 4 cylinder Chev motors? I have read about an overhead cam cylinder head, does anyone have one either for sale or for pictures?

I have a 1928 Chev sprint car under restoration and any information or ideas would be helpful

I have one. I was told it was made by Robert Roof. It is alledged to have been on a Missouri based dirt car.

Here's a good thread to read:

And, below is a pic that I took a couple of years ago. The OHC Chevy head is in a locked container box in the Stockton, CA area. Also in that box are other speed equipment, a 1925 Chevy block set up for racing, and a John Gerber-built motor. Most of it is for sale. This stuff belonged to the late Carl Schmid. His son now owns all this.

That is an interesting arrangement. It prompts 2 questions from me
1) what is the 1st lobe on the camshaft for?
2) was the cam gear or chain drive?

My question is that I cannot see all of the valves. Is this for a 28 Chevy head?

From what I recall, it is a '28 head and I don't know what the extra lobes are for.

Brian said that he didn't know the history of this head, so I don't know how the cam gear was driven. I believe he was asking $1600 for it.

He also has a bunch of the '23 OLDS 3-port heads. He'll magnaflux them and sell them too. I don't recall the price.

That head is either a single port Chev head,or a 3 exhaust port Chev/Olds 4cyl head,as the the inlet manifold exhaust heating port has a pipe plug screwed into it
