I used the Mallory centrifigal distribtor amd HyFire VI box It has the option of programing in the amount of ignition retard under 500 rpm (starting). I have initial set at 14°bftdc and have 10°plate in the distribitor = 20° totaling 34° bftdc. I have 10° retard so starting isn't a prpblem. I allso have the boxe's programable rev limiter set at 6,000 RPM for safety.

I bought the new Mallory HyFireVI and almost a year passed untill I could actually use it. When the Engine and all were done the engine idled just fine but after a few minutes of driving away from my home anything above an idle was terrible, I'd turn towards home hoping I'd make it, The engine would idle just fine but getting the car to move down the street was terrible, The car would idle just fine. I'd clean the fouled spark plugs and try it again. Mallory has a shorting plug (box bypass)I used the plug and the engine ran fine. I blamed the box. Just within Summit warranty period I returned the box with a note. The next Mallory HyFire VI box worked flawlessly.

I just checked the Summit catalog and they refer to it as a Mallory HyFire 6 control box. I swear it has a Roman numeral on the actual box. I have all Mallory FE centrifigual distributor photo triggerd ,mechanicl tach drive with small cap. Mallory active power supply filter. Mallory Pro Master coil. I started with an older HyFire 4 box with a seperate dial rev limiter that didn't work with the box and the lable on theold HyFier 4 box needed replacing. So that is why I bought a new Mallory HyFire 6 box and the active power filter.
