No Spark Question

For your car, there is a $45 HEI distributor on ebay. Simple hookup. Many here use it w/ no problems, though one guy said he saw a few have failed lower bushings. But, it has to get 12 V from the battery to work. Your Mopar ECU needs power too. Did you check that? No excuse for not having a multimeter. They are free w/ coupon at HF. Indeed, don't even bother posting until you get one. No sense flying blind.

BTW, if your engine is 1964, it is a 273, not a 318, but most parts interchange fine, except for intake manifolds.
