Two places:

Schneider Cams in CA. According to their website, they have the original lobe patterns for this grind.

They took over old time grinder Pete's equipment and lobe patterns.

Schneider Cams is an excellent source for the Potvin 3/8 Super. For the latest Ford flathead engine we are just completing the cam is the 3/8 Super from Schneider. Checking the cam timing which is critical to do for any flathead cam installation I can relate the cam was spot on perfect to the cam timing specifications. That's not easy to do when a cam grinder is reprofiling an original cam.

That's good news. The one Ronnie dialed in from my motor was ground by Bill Jenks at Moon. Let's just say it needed a little adjustment to get the timing right.

The Potvin Super 3/8 is a great sounding cam. I had one ground by Bill Jenks when he was still alive. It's still sitting in the box waiting for me to do something with it.

Great sounding and performing cam. I love it in my '28 AV8 roadster with a 292 c.i. motor. Pulls like a freight train and spins the tires in second.
