Gary Lewis Posted January 14, 2022 Share Posted January 14, 2022 Janey has been on a mission to get some of the many, MANY things stored in the attic above the garage cleared out. So today I was going through some of my things and found this. How many of y'all have used one? This one was on the 390 in my '72 F250. Link to comment Share on other sites More sharing options...
85lebaront2 Posted January 15, 2022 Share Posted January 15, 2022 Mark Ten, Mark Ten B and Mark Ten C along with their GM only breakerless conversion. Preston Carburetion was a distributor for them until they let anyone have them for less than my cost. I had one on my Shelby, one with the breakerless conversion on my Jetfire and sold many of them. Manufactured by Delta products. Link to comment Share on other sites More sharing options...

Manufactured by Delta products. I knew you'd know all about them, Bill. They sure cut down on the wear on the points. However, in a way they pulled too little current through the points since the points wouldn't clean up when fouled. You probably remember my story about running out of gas in one tank on the 390 and switching over to the other. But the engine wouldn't catch. Long story short, the high vacuum during the coasting time had allowed/pushed oil vapor into the distributor and fouled the points. I ran a business card through them and it fired right up, but that was after I disassembled the QJet on the side of the road, convinced it was a fuel problem. After all, I'd run out of gas, so...
