distributor choice

I run a Summit distributor that's made for connecting to a CD type of ignition (MSD, Pertronix, Crane, ETC..)

It is a simple installation, rock solid timing, and has an adjustable vacuum advance.

I was running one of the cheap *** Ready To Run distributors, and the mechanical advance would go out of control, and I saw up to 50* of advance with the vacuum advance disconnected. Not good on a 11:1 motor with forged pistons. LOL!
