hey guys,

Just got done with an ignition upgrade and took it out for a few test drives. The first two days I ran a sidegapped motorcraft copper at .054, then the past two bumped it up to .058. Took it out for a test drive with no stuttering or stumbling or trying to die on me, but still had it's familiar low power troubles in high gear (almost no acceleration if I'm in OD around 50-55 without pushing the gas right before the point of downshift). I climbed a few hills at different speeds and it climbed with no trouble once the AOD dropped a few gears.

This is an 89 with the 302. It's got a new MSD cap and rotor, 8.5mm MSD Super Conductor wires and an Accel 48k volt coil (.2 ohms primary resistance, 132:1 turn ratio). Timing is stock, the stock gap had been .044.

Would a misfire definitely be noticeable under these conditions? If so, would it be in the form of idling rough or shaking/bucking under load? Asking because when I first started working on this truck, I barely noticed that the #6 wire was disconnected from the plug. Tonight I'm planning on pulling one or two wires and seeing how it revs or drives to get a feel for a misfire with this engine
