If any input is appreciated, here's mine:

If your budget allows, purchase a MSD "E-curve" distributor. Then, you can use the very nice HEI type wires. And, you can ditch the ballast resistor and crude ECU.

Finally, you can "program" the advance curve and rev limiter.

I haven't initialized mine yet . as I am waiting on other (suspension) parts.

Electronics have "advanced" in 40 years - what they had back then was great, but why use it now ?
