Slim chance I know, but any leads on either cam?

Get the specs and have Ken at Oregon Cam Regrinding regrind it on an OE core. I am not sure if that is an option for you. If I needed that cam, that is what I might try.

Do those old Hyperpak cams have part numbers stamped on them?

Just go to any mower repair shop and grab a cam. Same thing. :mrgreen:

Here is the part#/ specs from Dan. I'd like to see the @.050 numbers. That also appears to be a lot of overlap?? But looking at other comments it appears that is about the range the hyperpak like.

Chrysler Hyper Pak camshaft part № 2205 620:
276° intake duration
268° exhaust duration
52° overlap
0.430" lift

All fairly good answers, except the lawn mower cam answer, that is totally wrong.

I have never seen one, or the Melling either.
Wondering if they exist.
Not looking for the easy button, looking for the real deal.

Y'don't say! I bet that's a very different proposition now than back in my day.
