Model T Ford Forum: Forum 2014: Original Fronty Blue Prints

I found a set of blue prints for a special Model A Ford crank, Rod, & camshaft. These were designed by A. Chevrolet, and drawn by his son A.C Jr. in April 1931.

Would these be for a stagger valve Fronty?

Thanks, Bill In Luziana

Thanks Mark, I appreciate your input. The blue print of the camshaft only shows 1-cam, and not 2, and this concerned me a little bit. As you know, the AF16 was a DOHC mill. Since it was a stagger valve design the I would think the second cam would have a different lobe pattern. No big deal, just reverse the intake and exhaust lobes for each cylinder.

Any other thoughts?

Wlliam

I thought the cams would be same for both sides, as both sides do the same thing at the same time? That's part of the idea of the stagger valve.
