Marked 00, 05, 08 from what I gathered in the valv adj documentation. Whats the difference between them (other than materials). More importantly, what do I want for hp gain?

A V8 gas car.

Changing the cam on a 617 diesel is not going gain much if anything.

edit:

I do remember sometime back here mention of head work, an "05" cam advanced just a bit and tweeking the IP yielding good performance and mileage. I did a search but came up nil...
If I remember it was in a W116 chassis. Who was that???

Both of your cars already have the later camshaft. The later camshaft was added in 1980 300SDs to increase the HP by 13 or so (my '79 has 110, I think you have 123ish?).

This document has a lot of info on the different cams, their valve timing, duration, etc. Comes from the MB engine manual.

Search for the name "Doktor Bert". He's done lots of interesting things to his W116. I bet that's who you're thinking of. Lots of good threads.
