Are Moper FSM Distributor Specifications Complete?

The big difference in CAP vs non-CAP is timing at idle speed; then they made up for it with the primary advance curve. I posted a comparison a few ago. Later they started changing the curves more as just posted by 67Dart273.

One downside of retarding the initial timing, especially when coupled with running leaner as they did, was increased engine temperatures at idle. That was somewhat addressed with idle solenoid so the throttle would close more when the engine was shut off. Other workarounds and changes to the concept were added over time to address overheating in traffic. Nowadays, the fuel in some locations (and times of year) is such that even fully stock engines sometimes have issues at idle/off idle with this setup. Its not about the octane - its about the fuel's distillation curve. I have no idea what your fuel is like - just something to be aware of if it comes up.

Since you're showing an magnetic pickup distributor for '72, I have to assume that is CAP spec'd and may be different than the 49 state version for that year. So those to can be compared too if your curious, and depending on what your goal is.
