i personally prefer NGK and Autolite plugs, use good wires 8mm+, use a the better brand when buying points if you keep it points make sure they're not some cheap made in mexico ones.... make sure you condensor is hooked up and grounded properly, make sure the cap is clean and free of cracks, same with the rotor, make sure the coil doesn't have any problems, check resistance, between the + prong and the - prong and check resistance between the +prong and the plug wire prong.... the first two should be incredibly high resistance, the second two should be low resistance..... make sure plugs are all gapped to specs dont just use out of box gap, make sure every single one is correct
