Going to autozone for the duraspark upgrade. Need help

[Anonymous]

Just want to make sure I buy the right thing

I have a 67 200ci. I am sticking with the stock carb for now but will upgrade to the 5200 later...

Which dizzy?

30-2690 (single vacumn)
30-2670 (dual vacumn)

What else do I need to pick up... Cap new coil gm module?

Thanks

Single vacuum.

Be sure to get a cap adapter, rotor, cap, and the 4 pin GM module.

Could you go with the dual vacuum and just plug off one of the ports on the dizzy? Then if you ever needed the other one you would have it.
