But RRR they are using big gaps like 0.060". My Motors Manual covers 1972-78. Largest gap in Buick section is 0.080". The Bosch HEI used here, 4 pin module similar to GM, used 0.065" gaps.
Trust me. There was a .120" spec on one of them. It didn't last long. IMO, the wide gap argument is useless. I think indexing is far more beneficial IF you want to go that far. I don't. LOL
