DoubleVision If you are only getting spark to a few cylinders by checking each with the timing light then you have a problem in the distributor as each wire should make the timing light put out a signal. First off, I don`t know what year vehicle you placed it into, but the HEI must recieve a 12 volt signal, so check the power wire running to it for 12 volts constant. If that checks okay then it could be anything in the distributor from a bad cap to bad wires to a coil, pickup coil or module going south.

Jmark Well, it's kinda time to go back to ground zero and start checking things.

You say you changed cams?
1. Are the timing gears set up correctly?
2. Are the valves too tight? Loosing compression?
3. Is the dist. installed with the rotor pointing to #1 wire when the engine is at TDC on #1 cylinder?
4. do a compression test. ALL low would make me re-visit the cam/chain install. Some high and some low would tell me to re-ck the valve adjustment.
5. Did you loose the ground to the HEI? Crappy spark will cause a timing light to not work, or work sometimes.
6. Is the HEI a known good unit?
7. Was the engine a known good unit? LOL

Just things to check. Sometimes it's good to go back to square one and see what got missed.
