Have a 454. Had it going like a month ago (cause it has a blown tranny) just to hear it rumble and well it ran for 30 seconds and then died. Cranked and cranked. Nothing. Gas in the carb and still nothing. So I went and replaced the cap, rotor and ignition coil. put it on top dead center according to the harmonic balancer. Crank it over and still nothing. So i took out the number 1 plug and grounded it on the header. NO F'n spark! The wire going into the distributor is not getting any juice either. PLEASE HELP!
