Moving along... time to put the new plugs in. Behold the infamous plug gaping tool. I don't know why, but I hate these things. They seem to be everywhere, and no body uses them. To use this plug gap tool, simply insert the steadily growing wedge into the gap in the electrode of your plug, then rotate it till it gets to the gap you want. I know what you're going to say at this picture.. .045" gap ~ that's too much! Easy tiger, the gap closes due to the metals memory. We ended up at about .040" ~ and thats because the coil I used is a little hot ~ aka high voltage. When gapping plugs, you want to make sure you have the energy for the spark to jump the gap and still be strong. The better the spark, the better the ignition process. The better the process, the better the burn, the better the burn, the more power your motor makes. After we're done with this leg of the test, we'll be installing a DUI distributor ~ and it's coil is even hotter (more voltage) than the one we have now. Bigger spark, bigger bang. With the plugs gapped the same, they were installed and we reached for the next step of this tuneup. That's right... PLUG WIRES. I'm going to be brutally honest here. I hate these wires. Okay, maybe that's too strong. I dislike them. SURE they're a good performance wire, YES they'll serve a long time. But.... ...if you don't have one of these. Your screwed. Guess, what. I don't have one of those. And that's a key reason I enlisted Ed to help with this. He does. So if you're in the market for doing a tuneup and don't want to buy a crimping tool to do it, have Jeff @ www.IHOnlyNorth.com send you some pre-cut/crimped wires. YES they'll cost a little more, but they'll save you about 1:30 minutes and the cost of a tool when installing the wires. That to me is well worth the $$ on the pre-crimped stuff. Anyway, the tool aside, this is one of the pre-crimped ends. This is what you want to end up like. Lets see how we do.
