I ran a Mallory Unilite for a while and went thru at LEAST 4 modules in the span of 3 or 4 years.

Wasn't worth it IMHO, swapped in Duraspark and never looked back.

Basically it (Unilite) ran fine most of the time, but you would go to start the engine and crank crank crank... I have had my truck since 1993 and the Unilite is the only thing that ever stranded me... at least I was in a Village Inn parking lot at the time, couldn't imagine in the middle of nowhere. The other few times it took a crap I was at home, so it was easy to throw in the points dizzy to at least get where I needed to go.

Mallory claims there are extremely sensitive to voltage spikes and what-not, but whatever I say they are junk.

While aftermarket parts are cool and sometimes an upgrade, for reliability, most of the time you cant beat stock. Most people dont realize that a LOT of the aftermarket stuff is built for racing applications, not durability. In race applications things are usually double and triple checked, repaired or replaced before each race, wheteher it be an 1/8 mile run down the strip or a 500 mile NASCAR race ....................Im not saying that the majority of the aftermarket stuff is junk or not worth putting on a vehicle. Just that it may have been intended for a different application where day to day, stick it in and leave it alone reliability isnt as big of an issue.

Exactly, if the Mallory takes a dump in the middle of Wyoming, Kansas or whereever good luck finding a shop with a spare Unilite, MSD or other module.

Duraspark modules and points are everywhere.
