How about fuel volume and pressure? Fuel filter? Do you have access to a known good distributor? Have you checked all grounds? Engine ground to chassis? One cylinder not firing exactly perfect would cause the eradic idle, but engine should still rev over 4500. Gotta get back to basics and try one change at a time. Dwell 28-32 (or pop in electronic to rule out dist.) timing all in by 3000rpm and 36 degrees for street should be good. Fuel pressure around 7 should be good. Could be a minute crack/cracks in cap and cross firing inside and invisible to the naked eye. Dead valve springs will cause same symptoms, as will valves out of adjustment. </div></div>

These are all good things to check. When the car had the choppy idle I changed out the points and the car would not fire at all. I fiddled around with the wires on the distributor and got the car to start then when I set the dwell, I got a spark when i put the screwdriver in to adjust the points. I think I must have a distributor wiring problem? Going to start with that and then work forward. One thing to keep in mind...when the idle was choppy/missing it would pull hard to 6K plus...ugh...crazy...will keep playing with it. thanks for the help
