If someone else comes across later maybe it'll help when running an HEI. Thought I'd share a budget friendly tech tip.

Since the recommended plug wire size is 8mm and most aftermarket sets are 7 or smaller, unless you're buying more of a premium set. Figured guys might like to know that stock Ford Fairmount wires are 8mm, I get them for an '80 when replacing wires on the Jeep and they fit well with the straight 6 and are usually less than $25 for the set.
