You never know what happened before you got it either.
I was getting a steady 28 dwell....but that was at .018 point gap. Anything less than that and I would drop to 25.Dwell is good?
It's better but still not quite right. I think it's in the carb now...could just be a worn motor. Getting 18" of vacuum at idle on the manifold port but it bounces some...could still be the timing chain. Going to replace that soon.Open it up to thirty so when it wears it drops a bit. Glad to hear it is good now.
I think mine says 28 to 32I could never get much more than 28 dwell. Maybe I am doing something wrong. Don't the specs say 30 to 35 dwell, I can't remember.
Most of it seems to be pretty good but I did notice the connector on the distributor wire feels like it could have several broken strands. I will be replacing that and see if that helps. I haven't messed with anything else in the bay yet besides the bulkhead connectors...but I will go through it. Ty.Unless I missed it, I don't see any mention of the condition of the engine harness.
Is it original/unaltered?
Have you physically inspected every wire for continuity/wear/defects?
All grounds good?
A now 52ish year old wiring harness has seen a lot of temperature cycling, and possibly/probably some cobbling from previous repairs.
Replacement engine harnesses are available from Evans Wiring Harnesses.
After I rebuilt the dash in the Silver Custom, I had a hot restart issue. Turned out to be timing off a bit. Try as I might, I could not rotate the distributor enough to get what I needed.
Another set of eyes discovered that the coil was not located in the bracket properly causing the distributor to stop before full travel.
A few adjustments, and it ran like a rocket.
Hope the input helps.

I have a 67 Polara small block car that I bought 12 years ago. I bought that Petronix conversion within the first hour of owning it. Couldn’t be happier! Literally haven’t touched it since other than replacing the cap. Highly recommend it to anyone! I think it was about $75.00 bucks back then.You can do a Pertronix in your points distributor provided that it does not have excessive play in it.
It will need a recurve since it was designed to run at low initial timing with a weak spark.
Speaking from experience,the Pertronix does work very well with a recurve.
Without a recurve it is ping city.
A recurve will allow you to run 10-12 degrees initial compared to the low 0 or 5 degrees factory setting and limit the total mechanical advance and allow it to come in sooner.
A total of 34 38 degrees all in at 3000 RPM.
383's like lots of timing whether you have a stock or better than stock cam.
I did electronic in my 318 powered 71 coronet. That car did not need a re-curve. But my 440 68 Ny'er and two 383 powered C's had to get re curved.I have a 67 Polara small block car that I bought 12 years ago. I bought that Petronix conversion within the first hour of owning it.
