OK! Not sure what I'm going to do. But if I did go with the 2280
How can I tell if the 2280 is computer controlled?
By definition a 2280 is not computer controlled. The model number for the computer controlled equivalent is the Holley 6280. Look for wires entering the float bowl of the carb.
How can I tell if was intended for a V8?
Almost all Holley 2280 carbs are intended for 318 use, but some were calibrated for use on a 225 slant six. The best way to tell is by the list number of the carb. It should be stamped on the air horn. You can look it up online. You may also use a Carter BBD intended for a v-8.
I would "Use an ordinary Chrysler electronic ignition distributor with a single pickup and vacuum advance." What exactly does single pickup mean?
All electronic ignition distributors use a magnetic pickup in place of the older points ignition systems. Lean burn systems use two of these sensors under the distributor cap. If you don't know what a pickup looks like, make it easy on yourself. You want a distributor from a Mopar 318 or 360 that has a vacum advance pod and only two wires, not one, not four, going under the distributor cap.
Would any of you know a part number or specific vehicle I can retrieve one of these from? I am open to buying new parts in order to get this van rolling sooner. Said NOS Mopar smallblock?
Any 318 or 360 distributor from a 1973-mid 80s truck or van should be fine.
HERE YOU GO! CLICK ON THIS TEXT! NOW!I would also replace the cap, rotor, ignition module, and coil. If you have suggestions for these specific parts as well, that would be great (particularly the cap and rotor.) I would also reference Reed's link for this info.I haven't replaced a distributor before, so any references to other write-ups on this topic might be helpful. Though I do have the Chilton service manual.
My link is specific to slant sixes, so the part numbers for the cap, rotor, and wires won't work on a 318. I do recommend NGK plugs, and get the best quality cap and rotor you can afford.
The Chilton manual is OK for a short term get-by reference, but if you really want to work on your van you should invest in a factory service manual. They aren't very expensive on eBay.
Swapping a distributor on a smallblock is a cinch. The bottom of the distributor shaft has a lip that runs across the diameter of the shaft. The distributor will only seat with the rotor pointed correctly or pointed 180 degrees off. Pop the cap, note where the rotor is pointed, note the orientation of the clips for the cap, unplug the leads to the distributor, remove the holddown, pull distributor out. Align the clips for the cap on the new distributor to the same orientation as clips on the old distributor, point the rotor in the same direction as the old distributor, and drop it in. Last step is to run the vacuum hose form the distributor vacuum advance pod to the correct nipple on the carb.
