One additional note. You need HEI style plug wires also. The old conventional point style distributor has different ends.

Buy them for a 75 Chevy Pickup with a 350 and you will be good.

Not just the ends, I believe they need to be at least 8mm (OEM points dist. had 7mm) to handle the increased current of HEI.

Also, re-gap your plugs from .035 to .045.
