Fuel injection for the slant six

My car still has the original style single-chamber master cylinder. It seems to work just fine. My neighbor was looking at the car the other day and stated that he thought I should upgrade to a dual-chamber for safety reasons. In opinions?

I see you're new here but this is a thread about fuel injection. There is a separate section for brakes.

If you actually drive your car then YES you should convert to a dual system. ANY leak anywhere in your brakes (lines, MC, wheel cylinders, etc.) and you have NO brakes except parking brake. And you're in the rust belt.

Before I even drove my 64 out of the driveway I converted to dual using a new MC from a 1967 A-body. 8000 miles later and my front end is still intact.
