Are Volvo cams clearly marked C, D, or whatever? Is there an easy way to find out what it is without completely pulling it out of the engine? Mine is still in the car, which is a 1963 PV544 with a B18D. Just wondering since IPD has D cams on sale right now, and I am tempted. I think mine is probably still stock, but not sure. I would not get to this job until Springtime at the earliest.

The C cam I pulled out of my B18 has C stamped on the end. Unfortunately not the end you see when you pull off the timing cover. The only thing I can think of is using a dial indicator and measuring lift. I recently measured about .285" of cam lift on my D cam. The C cam I have removed is really worn out and has about .250" of lift. I think a new C cam should have about .263" of lift at the cam.

Oh well, thanks! I think I will hold off on doing anything until I start this job for real.

A '63 B18D originally had a B cam. If you have the flywheel off (which is a big if), it's no big deal to pop out the soft plug at the rear of the cam galley and see. The B would me marked with a six or seven digit part number, not with a single letter.

Thanks Phil. No plans to yank off the trans, so I guess it will be a mystery until I take it out from the front.
