3.0 CIS to Carbs Distributor

I have a 3.0L SC motor that will be converted to 40IDA3C carbs from CIS.

Per the distributor that is currently on the car, I have read that a recurve is highly recommended. If I were to buy electronic ignition, is a recurve still necessary, can I use the same distributor or do I need a different one?

What about the vacuum? Do I need to plug it, remove it, is it connect-able to carbs?

I've been searching Pelican as there are past topics, but not 100% sure. My knowledge on distributors and ignition is newbish so trying to learn!

Yes, installing an electronic ignition would still "require" a recurve of the distributor.
Strictly speaking the engine will run with the stock distributor setup, but the recurve opens up a lot better throttle response.

If you buy electronic, like Electromotive, you pull the distributor and plug the hole.

Here is a pretty fancy electronic ignition set up.

Then is there any good reason to buy an electronic ignition or just use whatever is on the car now?

Unless you are going nuts, I would just have the distributor you have re-curved by someone who knows the ropes on what to do. It is not a really expensive process.

I would still classify your distributor as an electronic ignition vs a mechanical points set up. The Electromotive pulls it's timing references from the flywheel or the pulley at the rear of the engine (bumper side) and then that data is run through a computer/chip and the coils are told when to fire. Very cool, very smooth (once set up) but very expensive.

The SC distributor is a great distributor.

I usually recurve these to either a modified RS or a mod 67S curve when running carbs. It wakes up nicely.
