| When the OP stated changing out all of the MSD w/ exception of the distributor......is that cap and rotor/ wires/ plugs? Was the box replaced? If it's a red 7al3...that'd be my first suspect part. Have had 2 go bad in past years.

Is this a crank trigger? I didn't see if the phasing had been checked if so.

Then the rotor phase was checked? couple ways to do it easily.

| I agree when Shane said “With no data, man you can throw a lot of parts and money at this and may never find it”.
Even a Grid 7730 will show one the triggering In / Out pulses and rpm graphs to help decide if it’s ignition related.
If you replaced all the ignition components and related ignition wiring, it’s not ignition imho. |

I think it was meant as humor. Maybe?

| Just curious what year this “rail” was built and maybe how old the wiring is?

| I have to agree with Ed on this, I have had this happen & it WAS a converter each time years ago, the popping /cracking occurred & I did the same, Changed MSD, Carb, etc; all the above looking for a miss in the engine. After eliminating all that, we changed converter and it was fixed. Years later a friend was having this issue & doing the same ignition changes etc. I told him it appeared to be converter & sure enough, that fixed it. If the converter is broke & loads the engine and doesn't let it come up in rpms, it wont be happy. Its strange but can lead you to looking in the wrong areas to correct the problem. I even witnessed this issue in a mud bogger, & you would think the spinning in the mud would not show the symptoms but it was the same. |

| being that you have installed new, replaced or checked everything else, you've got nothing to lose. |
