OK.. I have reinstalled the intake cause it leaked and fouled the plugs... but it still has an intermittent pop as I drive...

It has new plugs, new points, new cap and rotor...   WTF could be making this pop..

You can hear it in the muffler as you drive.. like a little misfire.. Under acceleration there is no pop..

How is the play on the distributor itself? And how old are the spark plug wires? Did you do a check to ensure the intake isn't still leaking? From there, compression check for a leaking valve.

This all started when you pulled the intake originally right?

No .. I pulled the intake because I fouled two plugs with oil and it turned out to be loose intake bolts..

Then I pulled the intake and resealed everything.. now the pop is here and there..

BTW.. I run a Mallory HYfire 1 ignition and a Crane PS91 coil..

Double check the point gap.
Intermittent misfire can be caused by a bad plug wire.
6 years on the wires?? Change em.
The wires sold through Crappy Tire are actually made by Niehoff-same company who makes factory wires for Mopars.

Really? Good to know.. I was going to order some new wires from Mopar for my truck but I will get the crappy tire ones then...

I think I might get a make-your-own set for the windsor.. the bought sets are always ten times too long..

Maybe put on some 8mm wires?

Anyone have an electronic dizzy I could use in the 361.. I think it's time to swap out the points dizzy

Electronic ignition for a 361 is the same for the 383, 400 and 440, the rest of the engines never had it stock (too old), but they all fit inside the stock distributor, and then you have the aftermarket list that is almost endless.

And yes, replace those wires, six years is really pushing it since they have been broken from the sparkplugs more than once.

The distributor will have to be from a 400--or a modern conversion kit for the b engines.
the 440 dizzy will be too long.

Popping from the carb is usually lean condition.  Muffler farts is usually a rich condition.  Really rich.  Or I have seen carbon tracking or a cracked Disty cap cause that too

I guess I should have been more specific to a dizzy from a B-engine.. I know they are the same.. just didn't write it..

I'm starting to think about spark scatter... I might have another cap I can cut a hole in and see if I am out of phase... This could have started with the new cap last year when I changed the points/cap and rotor...   it was just made worse by the leaky intake..

I pulled the plugs and they look great. The 600 Holley is spot on what the engine seems to like based on the plug colours..

I'm thinking wires like you guys said.. visually they look good and only have 10 000 miles on them but who know how they look on the inside..

So.. as an experiment I unplugged the vacuum advance.. the revs dropped down... I had it attached to a timed port on the holley.. but for some reason it seemed to have a little vacuum at idle ( i think)causing the revs to jump up..

I took the car for a drive with the port plugged and the vacuum advance unhooked. The miss seemed to go away..

Can someone explain to me what might have happened/

The vacuum advance has a plate inside the distributor that pulls the point forward and backward with the change in vacuum. The distributor may have worn bushings, which may be closing the points more on some of the crowns than other, causuing a miss. Even if you have electronic ignition, if the bushing is worn and can move, the vacuum advance plate may pull against the plate a certain amount to cause the point/EI be more or less than the rest and cause a miss. This advance differs from the mechanical advance, which advances the rotor shaft itself vice the points/EI plate itself. It's a possibility.
