Slant 6 Turbo 68Dart Project

Thanks BIll. No matter what power it's making, it's still astronomical compared to what it was. I can get up to freeway speed before the onramp is over for once, and other useful things, plus a turbo slant is just... cool. I'll sort it all out, adjust my valves again, check and remove any and all leaks, and get her real smooth, then test again at 10psi. It should be a monster.

Right now I'm trying to figure out an appropriate gap. I realized after some thought that the last set of plugs i bought, I threw in there with the stock gap that came with the plug because I was trying to sort out a misfire, and a bit upset at the time, so the question is - what should it be?

A lot of people suggest .028. On NGK's website they suggest closing the gap .04 for every 50 more hp you intend to make, but an OG mechanic that comes by the shop often says that with my electronic ignition, the plugs should be opened out to .040 something. He does know his way around an engine and that's how he makes a living, so I am inclined to think what he's saying has some merrit, but is it applicable here?

So what SHOULD the gap be?
