Any advantages to locking out a mechanical advance distributor? Just curious.MSD Billet distributor with a 6CT Pro box in a dirt late model.

Imo, you are always better with some sort of advance mechanism, if only to make it easier to start.Quote:

Starting a crate isn't the same monumental task of starting a gas engine at 15:1 compression either. Then there are boxes that naturally retard, even with a locked distributor and those that don't. Blanket advice is rarely ideal, but sometimes best.Quote:

Just another opinion but reliability of parts is way more important. Weights come apart, stick, rust, spring break and wear out, etc.......
I have saw a lot of broke starters with a locked out distributor , I personally like a centrifugal advance , I set my total where I want it and start it on 10 degrees , then put the weakest springs on it so it totals quickly , at rpm , its the same as being locked out and easier to start , JMO ....now the new drag race control boxes are a different animal ....
Locked out.
Wire your car so you can hit the starter to turn it over, then turn on the ignition.
