A-Body Round #2- My '76 Scamp restore...
@Cudakid2967 you need to study a little more. Locked out timing is exactly that, locked out. If you set it to 15 degrees it’s 15 degrees everywhere. Idle, 2000, 5000, 9000 rpm it’s always 15 degrees. You’re correct that a lean burn distributor was locked out with no mechanical or vacuum advance curve built in, but your statement (and I quote) “the internals are able to adjust timing electronically” is absolutely not going to happen. Those distributors were controlled from an outside source, Just like using a locked out MSD (or any other locked out distributor) with a programmable box.
