OK, according to the manual, for a 1977 Ford truck with heavy duty (GVW is over 6000lbs) and California emissions, your 460 should have the following emissions equiptment:

- PVC Valve
- Thermostatic Air Cleaner
- Evaporative Emission Control (charcoal canister)
- EGR Valve

I do have a vacum diagriam, it's kind of hard to read, but if you PM me, I can scan it and email it to you.
