Camshaft identification....

27 Jun 2015 20:55

Anyone hear of or have spec.s for Cir Cycle camshafts? I didn"t know they even sold camshafts but I have one in an engine with Cir Cycle 35 stamped on the end and no idea what lift they are. Don't want to remove it to measure it so anyone know what this cam is?

I measured a lobe best I could and it looks to be .420-.425 lift. It's mated with a Web 109 which is .425 lift so it's probably close to being right. No idea what the duration is though. Jay from APE said Cir Cycle never made cams so it's probably a Norris or Andrews or something knock-off.

You could have it built up then grind and tap it. That's a pretty aggressive cam arrangement.
