Factory Tach Dash Question

[Duro5341]

Hey Guys

I have been reading alot about the 80's factory Tach Clusters....I want to find one

Now my only question is.....

I have a 86 Custom Deluxe, with a 350 carbed Heavy Duty Emissions engine....Whats this Feedback Carburetor there talking about. Mine has an electric choke, but thats it, no other wires going to the carb

it's a bare bones truck, no cruise, A/C, 2 speed wipers (no delay), manual windows, locks.....absolutly nothing. The carb looks the exact same as our 85 plow truck with a 350 carbed.

If anyone has more info on this, or what to look for, maybe I am missing something

Thanks
Cameron

Well I have looked over the truck, and come to the conclusion.........

I do not have a feedback carb, nor do I have a ESC dizzy....

There are no knock sensors, o2 sensors, nothing behind the glove box of any sorts....just the bare heater box

So it is proven a bare bones 1986 truck can have a straight HEI dizzy, and a simple carb from factory
