Anyone try these distributors?

They are indeed very good.
Not everything great has an MSD sticker on it.
It removes clutter, and GM HEI is a great ignition.
I am using one in my 408.

POS,

Have you used this dizzy with any type of rev limiter or retard box? You are a NITROUS guy so I figured I would ask.

Also can you dial the curve in and limit the advance? If so How?
You won't be using the vac advance correct?

Never ran one so I don't know and that is why I am asking.
