Is this correct.
2. Wish to replace the Mallory distributor with a HEI. I find lots of them for sale on e-bay. Would like one that is one wire and has a tach drive outlet. and is not a computer motor unit.
What do I look for?
An HEI will drop right in 1 wire hook up. Im not sure about a mechanical tach drive. They do have a tach terminal that will drive an electronic tach. The Oiling pad on the old dual point is to lubricate the cam the the point rubbing block rides on to extend the life of the block. It requires special lubricant that usually comes with the points.
On installing the HEi it does require full battery voltage. A lot of the older cars had a resistor wire feeding the ignition circuit when the engine was running. This would have to be replace so you have a 12 volt supply. This usually fed off of the r terminal on the starter. this is usually the only modification that is needed to drop in an HEI
