I'm not sure, it's been a while but I think it's a 2 barrel. Take the breather off and look down inside the carb. There will be 1 or 2 "holes" going down, these are the barrels.
Putting a larger carb on it will require an adapter plate. I do recall back in the 80's seeing an adapter plate for a 4 barrel for a slant 6. Probably your best bet would be to get in touch with a company like "Summit Racing" and see what they have available.

The great Dodge slant 6 engine...these were very strong and dependable, i put 300,000 on a 1985 D100 and it was still going strong when i sold it. Your transmission is a "883"
Chrysler began using "833" four speeds in passenger cars in 1964. The transmission was designed by Chrysler and manufactured by New Process Gear Co. Chrysler installed the 833 four speed behind the Slant Six at two different times. The first production four speed slant sixes were the 1964-66 A-body four speed cars. The second run of production four speed slant sixes began in 1975 with the release of the Overdrive A-833. From 1975 until 1987 the Overdrive four speed was installed in slant six applications of A-bodies, F-bodies, and light trucks (D100 & D200 series trucks). These applications were not ultra rare, but the slant six four speed production figures pale in comparison to the number of V8 cars that received A-833 four speeds. Since the A-833s installed behind slant sixes were basically the same transmissions installed in the V8 cars, a slant six owner looking to install an A-833 should be familiar with all the A-833s produced, including the ones used behind V8s...There are several characteristics of the various A-833s that determine which four speeds fit in which chassis and with which engines. For the passenger cars, Chrysler manufactured two different length four speeds. The A/F-bodies received a short tailshaft A-833 and the B/C/E-bodies received a long tailshaft A-833. This difference is obvious when one of each type is sitting side by side, but either type is easily identified when it happens to be a stand alone unit.

If you are looking to replace your truck tranny, you will need to find another one out of a truck that had the slant 6 engine for it to be a direct bolt up. Chrysler made several variations.

1975 thru 1987 Overdrive 3.09:1 - 1.67:1 - 1:1 - 0.73:1 (Trucks used a 0.71:1 fourth)

Good luck, hope this helps.

go to autozone.com. become a member. and look up the vacuum diagram for your particular yr, engine, trans, ca or 49 state.

If you go to AutoZone.com and register (free) you can nagivate your way to the "repair info" section. Once there look at the list in the center of the page and click on "emission controls:, after that look on the left side of the page for "VACUUM DIAGRAMS". the proper vacuum diagram should be there for your truck.

Need number off trans Is it a top load shifter goes right into trans or side linkage. If it is a side linkage 3 speed with overdrive (4 speed) it is a A833/Overdrive 4 (no granny gear just normal 1st gear) Otherwise it's a top load NP435 or NP445 the last two are HD units Your truck is 2wd with a 225 (3.7L) slant six and your the 7th owner

Cylinder one is up front.

you need to replace the fuel filter.

ok ... it could be that the carb is so gummed up with old fuel that none is getting into the engine..... some trouble shooting will be involved if you buy the vehicle
