Spout connector. Huh? Yea i made sure i removed it and remembered where i put and actually remembered to put it back in. That stupid little jumper should be 10 times it's size with a flasher on it.
I bought the truck and it started hard and ran like crap. I noticed it had a new diz and thanks to you guys i checked timing first. -6 and it ran horribly. Set it at 10 deg. and it ran fine so i decided to bump it up to 12. Has run fine at 12 but i wanted to play around with a vac gauge so i bumped it to 14 deg. and idle came up to 800 from 750 and vac went to 20" from 19. Anything above 14 degrees and my idle starts to shoot up to high. I also have an old msd5 box and blaster ss coil with the plug gap opened a little. I'm not sure if that helps anything? I don't think they're the strongest ignition pieces but they were laying around.

I just did the 6litre mod last week (minus the timing advance), I noticed a big loss in low end power. I regapped the plugs to .052 instead of .055 to see if the gap would help. I thought maybe the gap was intended for copper plugs and was too much for the platinums. I haven't got to test it yet because after reducing the gap I forgot to put my drain plug in before adding new oil during my change. 
Now I'm waiting for my dear old mom to get done with my dads car (her's is getting body work done), so I can drive the 20 minutes to buy more oil. Talk about a rough weekend.

If I was buying new plugs, I would go with copper. I just didn't want to replace plugs there were only a year old. I do plan on doing the timing advance, I just wanted to verify that the truck still ran ok, before changing something else, that way I have an idea where the problem is.
If the .055 gap is to wide for a platinum plug, then why would reducing the gap be a bad thing?

As far as platinum plugs go, they're not only overpriced and perhaps gimmicky, but seem like they don't do crap for our small block Ford engines, which is why most folks stick with the $1.09 Autolites or Motorcrafts. If'n I was you I'd just stick to the basics on the 6LTU, follow the method to a T and use the parts they recommend. If you only go half-a$$ed, then you will be both disappointed and losing money ( lower fuel economy). Remember, there's no such thing as being sorta pregnant....

Jfc, they're just spark plugs...it's not like you're replacing the tranny or a wife or anything...

In that thread, the author kept is motorcraft platinums. I'm sure he's not the only person to do that. I'm not sure you can not stick to the basics on this mod, the whole thing is fairly basic. Maybe your not the type, to make a few adjustments, and see what sticks. As for me, I'll play with my plug & gap combo a bit.

Well, mr ricky. I suppose I cannot say that I read through that entire thread. I will concede defeat on this matter. I have read a few more pages in, and am still working further through the thread.
While no totally thrilled with your methods. I get the point and will be replacing the plugs this week.
