Oh yes I should have added. In the crate engine section of Summit Racing cataloge they have a HEI dissy with plug wires for $100 bucks. Basic unit that I think will do fine and I will buy. To drive 45 minutes to an hour to the local pull a part and paying for the part will cost more in gas, time and their cost of the part. Can't beat that for $100 bucks. I have seen these $100 dollar units in use before and they seemed to work good, just not sure how long they will last or give problems?
