Looking for more pep off the line

There you go. Time to learn.
Chrysler ignition modules still require the ballast resistor. HEI and Capacitive discharge ignitions provide their own control for coil current but that's not what's on your car. So it needs a 0.5 Ohm resistor to protect the coil.

Medium springs have now messed up the advance curve. I can say that even having no idea what brand of spring or what distributor they were intended for. The primary spring provides enough force to keep the timing from advancing until above idle speed. As shown in the link I provided above, minor adjustment to the spring force is available. The factory primary springs all have relatively low spring rate, allowing a very fast advance from off-idle until 1400 to 1800 rpm. There is a lot of off the line performance right in there. The secondary or long looped spring then slows the centrifgal advance because the combustion is getting more efficient with more heat and faster burn rate.

edit:
Link from above: See post 17 for adjustment to initial force (rpm advance begins) Distributor curve help needed

I went ahead and took apart 4 distributors including the one on the car. Current dist has the gold weights, other one has bigger weights with the long spring. I figure the other distributor would be more of what I’m looking for. I also got 4 vacuum canisters, 2 are adjustable with 11R on the arms, one has 9.5 on the arm, the last has no stamp but a 5 cast on the body. Time to make one good distributor out of 4.
