This might be a compound problem and a long post to get the info on the table so thanks in advance for reading...
Alright, it is a '67 Dart with a 225, Holley 1926 carb, 3 speed auto and pizza cutter tires, the problem lies on the idle/driveability side.
After a 1,500 mile road trip the engine was acting jumpy and sluggish at stop lights, so I put a light on the timing and found the marks jumping around, no big deal a new chain and rebuild the carb while I'm under there, right.
So it turns out the carb is the wrong model, it is still a 1920 but the last few numbers are not found in any book or parts store anywhere. I rebuilt the carb with the kit for the right carb in hopes it would work anyway. Okay, now the carb is done the chain and new gears are on but it does not idle or drive without misfiring.
It had an electronic ignition gadget in the distributor and cost a lot to replace any of those parts, a reman points distributor only cost 40 bucks so she got an old fashion distributor. No luck.
During this process I found that the firing order was completly opposite the specified routing, the number one wire and number six were switched along with the rest. She ran this way for thousands of miles but I can not fathom how it is possible since it will not run with the proper firing order. The rotor does point to number one on the cap at TDC but after that it stops making sense.
The dwell is set to 42 degrees, I replaced the ballast resistor, cap, rotor, wires, plugs and even double checked the timing chain to make sure it was still lined up. My compression tester seems to have broken but I think all cylinders are sealed.
The timing still jumps around and the car stumbles horribly under load, it hurt just to move it out of the way.
I was thinking maybe the carb (needs the right one), the harmonic balancer rubber is gone, maybe the coil (tested okay) or possibly.....
If you made it this far thanks for bearing with me, hopefully somebody out there has run into this before, I am out of ideas/money and have started to doubt my mechanical prowess, please help!!!
