vacuum diagram help

The one on my truck is pretty much there, but missing a few areas. It is on a 1984 F250 460 4x4 non-catalyst base model. Would anybody happen to have a complete/legible one that I could print off?

I will be the first to ask
Do you have all the parts and just need to know how it gets hooked up?
Do you need to pass a smog test and if so do they look under the hood or just a sniff test?
If you say no to either or both it might be best to just hook up what is needed like vacuum advance, power brakes, HVAC just off the top of my head.

You must have a truck that was built for Canada. That is one of the simplest 460 diagrams I have ever seen. Most of the 460's are terrible when it comes to smog hook-ups, dual smog pumps and all kinds of junk.

That one is close, and what I have been using for reference against mine. Smog pump has been removed along with the ABV, no TK, no purge and the air cleaner stuff is shot. Still has the EGR and VCV's running a Holley. Truck was built in Minnesota.

I think it is beyond that point, but will double check today.

So if everything has been removed or not hooked up why do you need the vacuum picture?

Because I want one to print off for the valve cover in case a future owner goes and restores the truck to original.

So I routed the non-ported vac on carb to the 2 barb VCV to EGR, Manifold Vac to 3 barb VCV to Distributor, PVC to large port on Carb and capped off other vacuum sources.

Are you good now? Is this the diagram you need? I might have a cleaner document for you, but that blasted photobucket logo is obscuring the number I need to search through my book.
