I'm not real clear on what's going on here with your '78 as it sounds like there are multiple issues going on. If you might be somewhat clearer in your description of the problems, we might be able to be of more help.

If the engine binds up on cranking and goes free if the plugs are removed, the engine is seriously out of time. Instead of compression building up in cylinders the orderly fashion that allows the engine to run properly, the timing is so far off that it creates opposing compression and binds, or seizes up if you prefer, the engine. With the plugs out, the compression has someplace to escape to and the engine is free turning.

I'm totally confused on the starter problem, if there is any.

The starter is a gear reduction direct drive...coupled to the engine through a chain to the clutch.

With that info,there are only 2 things that come to mind...Either the clutch is not grabbing......OR....the starter gear drive is slipping.

As I recall the outer gear ring in the starters planitary assembly has a shear pin in it.
It may be missing,or if it's a knock off starter,the assembly may be broken. (low bid material)

It sounds like,by your description of being able to crank it wit the plugs out,your starter is not coupling with the stator wheel effectivly.
Its slipping somewhere.The starter motor is turning,just not getting to the engine.

Starter or clutch,and you did the clutch already.Take apart the starter gearhead.
