I have a 302 with 351w heads, roller rockers, Mallory Pro Master coil, Unilite 9000 distributor, and a Edelbrock 600 carb. My trouble started when the engine would just suddenly die with no warning after running awhile. I've replaced the fuel line and filter. I installed the new Edelbrock carb thinking the old Holly had seen its better days. I can see fuel through the clear filter and watch the carb squirt fuel in the bores. Still no luck. I replaced the spark plugs and set to .35 and replaced the old Mallory coil with a new one. I even checked the valve lash as a last resort. Occasionally it will fire up like today and run for a minute and die before I can do anything. I've tried adjusting the timing while someone else is cranking too. I have only the spark plug wires and distributor left to replace. Any ideas because this is becoming an annoying and expensive problem. Thanks

Unilite....

Put a stock distributor in and see if the problem goes away...I'll bet it will.

Then, get a Pertronix kit for your stock distributor if you don't like the hassles of replacing points once a year or so...(personally, I don't mind)...

My last unilite ended up as an oil pump spinning fixture...*G*

I've been running my Mallory Comp 9000 for about 11 years now. I haven't had one bit of problems with it. And I haven't been to kind to it *G* With my 351W, I take it up over 7K with no problems. On the other hand maybe I just got luck. LOL

I was leaning towards replacing the Unilite anyway due to the operation of the mechanical advance seems be working incorrectly. I keep ya'll updated. Thanks for the advice.

You're among the majority of folks, IMO, who have had zero trouble with their Unilites...

I personally had 3 fail, one on my street racer back in the late 70's and two on early race car engines...once I switched over to Autotronics ignition components, I never had another in-service failure...

That and anecdotal info from other users and racers just led me to believe the failure rate was high enough to not warrant continued investment in their products....and this from someone who used Mallory religiously (I still have an old Voltmaster MarkII coil on the race car)...

It should be noted that all my Unilites were retrofit kits, not factory produced distributors...

I second your suggestion Camachinist.

Lose the Unilite, go stock and put in the Pertronix....
