Just finished tear down rebuild of my 454 gen vi. Installed new comp cams hydraulic roller cam and lifters, new springs, seals, retainers, roller rockers, timing set, head work, and my old msd 6a box that test good, new blaster 3 coil that sparks, and 8555 distributor with new mag pickup, rotor, and cap. Spark out of coil, still wont fire engine even with new cap and rotor. Mag pickup gapped to specs. Maybe i need an outside opinion, did i overlook something simple cause im tired? Haha need help got fuel no spark out of ideas!
