Custom built 65 Dodge Coronet 440 with a completely custom built 1969 440 Magnum bored slightly more than 0.60 over with large forged crank, forged cam and forged pistons. Runs with 4.500 stroke. Bought a new distributor from ASSAULT RACING, KMJ Performance. It has both a mechanical and vacuum advance and the high performance coil allowed me to dump my ballast resistor and my Electric Control Module getting rid of unsightly wires. Runs beautiful with no ping @ 180 water temp at 70mph and 40 psi oil pressure at idle. It starts no problem and I believe I've accomplished all I can with vacuum but I feel the timing "could" be adjusted however slight it may be to be perfect. LOL. Anyone familiar with how to adjust a mechanical advance???
