a simple replacement for the 2v set up is the edelbrock 318/340/360 performer intake with 1405 edelbrock 600cfm or the newer model edelbrock annular dishcharge 600 cfm carb along with the edelbrock mopar throttle lever adaptor.

this will bolt on a 4v intake/carb that hooks right up with the stock throttle/PTK linkage and adjust out properly with a slight adjustment to the 2v carb flat slide bar(I bolt 2 together to correct length).. finding the 4v q-jet PTK linkage for a truck will fit with out mods and also opens you up to a edelbrock RPM air-gap intake and edelbrock carb if you need more for it.

my 85 360 headed 318 has rpm air-gap intake and edelbrock 750cfm carb stock q-jet PTK linkage.

also a stock 4v intake and a mopar q-jet & linkage is what came stock on 4v trucks so that's is a direct stock package on a 360 headed 318 or the 360 engine in trucks.

find the stock intake and you can buy a reman q-jet for the 85 truck about the same price a performance carb runs.

it will work with the small 318 port heads and the edelbrock performer intake is the best fit on those heads as they have a necked down runner for the 318 and requair porting to open them up to 340/360 port size.

a q-jet will fit the edelbrock 318/340/360 performer intake which is even better for a mopar q-jet/linkage set up.
