[weaponoffreedom]

Looking at an ignition upgrade

1999 7.4

Best parts, most reliable, money is not an issue. factory setup, no coil over plug conversion

any suggestions?

AC Delco, Davis Unified Ignition. Stock system delivers a fat spark at whatever rpm your 7.4 is turning. Ignition upgrades are for forced induction and/or high rpm applications.

I've never had an issue with ACDelco caps, but for my next cap I bought a UMP cap that others seem to be having success with. I've got UMP wires, LS style UMP spark plug shields, ACDelco plugs, and original wire retainers.
