I NEED THE FIRING ORDER FOR A CHEVY 454 BIG BLOCK AND THE LOCATION OF THE NUMBER 1 WIRE IN THE DISTRIBUTOR CAP. I ALSO NEED TO KNOW HOW TO TRACE THE WIRES THAT HOOK TO THE COIL. THE ENGINE HAS BEEN CONVERTED TO A MALLORY ELECTRONIC IGNITION. WE HAD A MAJOR WIRING MISHAP AND BEING A STUMBLE BUM AT THIS I'M REALLY AT A LOSS. ANY HELP AND ADVICE WILL BE GREATLY APPRECIATED AND YOU WILL RECIEVE 100 VIRGINS WHEN YOU GET TO HEAVEN. deeslaurenray@aol.com

Doc here,

The Fire order will be 1 8 4 3 6 5 7 2...direction of rotation is clockwise, and the #1 plug tower normally sits between 5 and 7 O' clock on the stock location...

but you can time it anywhere you may need for a clearance issue...just set it for TDC, marks aligned, compression, both valves closed..say you want it at 12 O'clock, just reset the dizzy body there, then rewire the cap to match..

Is this HEI or points?

To trace the ignition wire you need to test the wires adrift
(I assume you have some unhooked wires from your post...that you have no idea where to hook them up..)

Use a DMM and look for wires with 12 volts and on all wires that are switched and mark them as such...those will be the wires to confirm, you can ohm between them and the ignition switch.

If it's points, you will need to hook the wire up to the coil, and jumper the points to ground, and turn it on...measure the coil..It should read 6 to 9 volts...If not (stock system) you will need to install a resistor on the coil power side between the coil and the wire.....or you'll burn both up in short order..If HEI skip this.

If points (and also test on an HEI) You will (may) need a secondary ignition wire, (on HEI measure with DMM and see that the 12 volts stays during cranking.) If drop outs occur, you need to run a wire from the starter solenoid "S" terminal to the joint where power and the resistor tie before the coil..this will provide power during cranking for the ignition...

Doc
