Does anyone have any vacuum diagrams? I'm looking for one that is for the 91 with the 5.0 TBI and an older year with the carb's setup. I'm trying to make a decent merge of the two systems now that I have a carb'd 350 in mine now.

 

Autozone does (or at least used to) have some of them online.

 

Route them anyway you like:

1) line to brake booster - should come off large port on back of Edelbrock carb
2) line from front pass small port on your Edelbrock to the vacuum can on the distributor
3) line from the larger center port on the Edelbrock to the PCV valve
4) cap the smaller port driver side on Edelbrock
5) line from the intake manifold vacuum tree to a check valve that splits - one runs to hard plastic vacuum line that goes through firewall near heater box, other runs to driver side fender where it runs to the vacuum ball under the driver side headlight.

That should be it, unless you retained AIR or the EGR system.

One more - if you retained the heater diverter valve - run a splitter from the line that runs through the firewall at the heater box, and run a line from the splitter tothe heater diverter valve.

No pic - but Hope that helps!
