Default Re: 56 T-bird rebuild

Hall effect switches are breaker less and they are only as good as the quality of the magnetic pickup. Generally they are very reliable. Modules, not so much. The GM HEI is still the most reliable I've ever used in a distributor set up but they are big ugly things (the distributor).
