Hi.
Everything you need to know may be found at Ford Six Performance: The Web's Leading Resource for Ford Inline Six-Cylinder Engines and Cars! in the 240 - 300 forum.
It is a relatively simple process.
You need to eliminate the high pressure EFI fuel pump and use a low pressure pump such as a Holley or Carter. Or you may open a hole in the side of the block to use a mechanical pump - the lobe is still on the cam and the boss holes are there. You will need less spark timing because of the 'fast burn' characteristics of the EFI head. Depending on what exhaust manifolds you use some mods may be required to the intake. Good luck.

I'll add that the '92 van 300 will be running at 12v for the ignition, which you won't want for anything older than a TFI coil set-up. When I put my 300 into my '79 Bronco, I used a newer 300, removed the top end, added a Duraspark II ignition (Bronco already had DSII, so the ignition was already resisted), pre egr carb spacer, intake, and carter y carb, and kept the efi exhaust with a Walker downpipe. I also used the TFI coil with a pigtail assembly spliced into the DSII wires. Oh, and a manual choke. My engine doesn't have any rats nest on top anymore...great for troubleshooting in -30F weather.

I just dislike the look of the computerized style. I do like that sponsers product since it is all in a single piece unlike the stock Ford electronic ignition. I just don't care for the wirey look that a modern stock ignition has. And I have driven with points throughout all season up in Canada without problem.
The only wire you need for a point system is a hot wire running to your ignition switch from the coil, then wire the coil to the distrubutor and make sure the coil is grounded. All you need to set points is a feeler guage, some emery cloth, and a screw driver set it every oil change and good to rockNroll.
