Ok, I just picked up an 89 c350 centurion with a 460 efi,
After looking into what I thought was a bad water pump, I'm not replacing a stretched timing set.

I'm thinking about a cam upgrade, any recommendations?

I am only going to be using the rig for towing, and I do live in California so I do need a smog legal, and computer compatible cam.

Is it even worth doing?

Thanks for any assistance.
I've been searching the forum where I'm finding crane part numbers that no longer exist.
