The one you listed is mechanical advance.

The one you listed is mechanical advance.
Can't it be changed to lockout though. I just got a 85561,(slip collar) and you can remove the advance mechanism and lock it out.
I have an MSD pro billet. It has mechanical advance that is all in a little over 2K rpm.
You can also lock it out with a washer from MSD.
I also have a HEI dist that is set up as a trigger only. Locket out with an MSD coil.
Let me know if you are interested.
