Hello all.
Trying to get this 1986 F600 dump truck with a 370 up and running. It's been sitting for a while so I took the carb off, gave it an overhaul, and reinstalled it. A few of the vac lines were already disconnected and the Emission/Vacuum Routing sticker on the valve cover is missing. I've looked online but can't find one.
If someone DID have a picture of that Emission/Vacuum Routing sticker for a 1986 370, that would be amazing!
As for the Holley 2380EG carb on it, I'm trying to confirm where the 3 vac ports should go. I "believe" that vac port #2 in my pic is the Timed Spark Vac Port.
For ports #1 and #3, I'm not quite sure where they should be ran to.
Need to know if the emissions are Cali or not (I imagine you have no idea on that as the sticker is missing)
That #2 sure looks like venturi vacuum used for EGR (Cali)
Certainly #1 is manifold vacuum and it looks like #3 on yours is spark port
The bottom connection tube is the "Governor Vacuum Tube" Despite being a different carburetor, I think they share the same vacuum connections...
I hope this helps!
