Also not sure if the 37 had a resistor in the ignition rotor, if so then you shouldn't run resistor plug wires, if you are.

You can also check the ohms on each plug wire and see if one or more of them is way off compared to the others.

I have a multimeter that can also check rpm, dwell and a myriad of other automotive items.

But as other said, check for vacuum leaks as well. A can of brake cleaner, carb cleaner or staring fluid can help to find those on the intake.

Weak coil, dirty points, point gap, all the usual ignition gremlins. If the timing is moving around a bit, couldn't be distro wobble.





Also plug cross firing.
