Gary Lewis Posted June 29 Share Posted June 29 Gary, I wouldn't know, I never owned a GM vehicle with HEI. My 1963 Jetfire had breaker points until I put a prototype electronic trigger on my Delta Mark 10B in the distributor. All my other GM cars were Diesels. Ok, I was thinking that there was a recall or TSB where GM realized they'd put too small of wire in the harness to the HEI. Delta Mark 10B. Still have one of those. Put one on that 72 F250 but kept the points. Link to comment Share on other sites More sharing options...

Ford did build the early V8 units with ball bearing breaker plates. I had one on the 1957 312 I had in my 1958 F100 and one on the MEL 430 I had in my 1958 Country Squire.
