Camshaft Question

The 221 001 is not a part number of the era. Mopar part numbers that I have run across are 7 digit numbers. Space permitting, there are 4 numbers, a space, three more numbers.

I used a Purple Shaft on an engine rebuild that had what looked like a dark purple dye on all of the non-friction surfaces. This shaft does not look like what I had.

I'm away from my books right now, but will check and give you an update when I get back to them. BTW: If it runs in a 340, it will run in a 273, 67 & later 318, and a 360, too.

Other than the marks on the snout of the cam, I can't tell if it was previously used. Could you tell me what it came out of?
