HEI, I would go for .45. Kind of a standard number that balances performance and long coil life.

With the standard HEI, go with 45. If you have a aftermarket unit, 55.

How about a 74 with Delco point type Dist? (no HEI)

You are not supposed to gap a platinum plug because it ruins the platinum electrode.

Believe they come pre-gapped but I did check mine, all at .45.
