I had similar symptoms in my '77 (Da Rust Bucket) that got as bad as you describe: 
mostly missing/lurching/bucking, and I also had it die on the freeway a couple of 
times, wouldn't restart, etc.  I convinced myself that the wiggling I was doing on 
various harness parts and relay connections was related to the cause of it, since a 
wiggle would "cause" the engine to miss, or it would restart afterwards, but I could 
never *quite* track it down.

What finally cured it completely, totally and instantaneously was a complete set of 
new, high-quality Bosch spark plug wires!  (I had even bought off-brand ones, and 
that *didn't* do the trick.)  So if your rebuild has not included new 1st class 
spark plug wires, give 'em a try!
