Hey, I just brought home a '64 Cuda. Originally a v8 car, converted to slant 6 after 273 blew up apparently. First try on a battery after going through a prestart check and lube of the cylinders produced no sound whatsoever. Found a broken NSS and fixed that. Cranks over now but no spark. Replaced coil, condensor, and cap. Checked all 6 plugs, no spark. Ideas?
