Are hei distributors better than regular distributors?
HEI is not just the distributor, it's the entire ignition system and yes, they certainly are better. Plugs last longer, fuel burns better and there is quite a bit less maintenance. The differences are that the coil of a HEI system has to run on a solid state module which is usually mounted somewhere outside of the distributor as opposed to the older style which runs on points that are INSIDE the distributor.

How do you fit HEI ignition into a 1955 Chevy Do you need to move the small block 350 engine forward or modify the firewall?

What do you need to change from points to electronic ignition?
There would be a steel resistance wire or some sort of ballast resistor to limit incoming voltage from the key to the hot side of the coil. That would need to be eliminated when switching to HEI. Also, HEI requires minimum 8MM spark plug wires. Then just switch distributors or install the HEI module in the original distributor, and you're good to go.

The gap is different for each type of ignition system being used. The old points-type distributors worked fine with .035". HEI needed more, up to .060" depending on the year. You can usually find this info on auto parts stores websites if you know the year of your ignition system.

Yes, a disconnected or broken TACH wire from the HEI distributor cap can cause a '79 trans to fail to start.

Will the distributor plug wire set up be the same for HEI ignition and non HEI Not sure of the year Chevy 350?
The wires are different - HEI ignition wires won't work in a standard distributor - they all go in the same relative places though.
