ignition upgrade and timing bump (no 56K) - FSB Forums

 

Copper plugs are better.

The difference is gapping the plugs at .54 and advancing the timing slightly.

 

It involves hotter ignition components (except plugs, always stick with Motorcraft copper core) and a timing bump to 12.5-13.5*. I used Ford Racing wires, MSD Cap, Rotor and Coil. Than Motorcraft copper core spark plugs. Runs like a champ. Brought a little more life out of the engine.
