    Rated 5 out of 5 by from Worked perfectly I replaced a billet high performance eBay distributor with this one and WOW what a difference! I had popping thru the exhaust at about 4K rpm with the new old one and this one is smooth as glass, 10:1 comp 350 with a fairly large cam, so don't think the price of this makes it low quality it works great

    Rated 5 out of 5 by from HEI GM Complete Unit Very nice unit. Works first class first time! Placed it on our 327 engine that had not run for years. It had a old HEI with a bad module decided to get complete unit and glad I did. Got more voltage with new unit.

    Rated 5 out of 5 by from HEI GM Complete Unit Workmanship is very nice including fit and finish. Very pleased but wished it was made in USA instead of China. Also instructions would be nice if included firing order but easy enough to look up. Know most applications you were swapping out unit but not in my case.

    Is the cable that connects to the cap replaceable? My black connector is broken and I'd like to fix it if possible.

    Asked by: Ryan_e
    Unfortunately, we are unable to get this wire. We can only get the power leads to it.
