    Did you remove the coil packs - this will help a lot if you can get to it from above? It's a pain to get to, might even try from underneath with another person helping from above - depends on your header type. It can be done though - just takes some patience.

    Underneath with another person above helping. Best way to do it IMO for your case.

    also make sure to use one of those swivel pieces in between your extensions. Took awhile, but finally got it off. I also had moved the coil packs out of the way.

    it takes a long time...that one plug took me like an hr the first time before I finally got it off (when i still had stock manifolds). And trust me, there was alot of bitching and fighting with it. Now its alot easier (comparatively) with LTs.

    Just out of curiosity, what tools are you using to try and remove the #8 plug? Also, do you have a pic of the passenger side of your engine bay?

    Not sure with your style headers, but getting at No. 8 from underneath the car, or with the coil packs removed, was a lot easier than I thought it would be. Also, a 1-1/2" extension for your 3/8" ratchet works really well for plug changes. Curious to see what you are dealing with for space. +1 -- pics would be helpful.

    Open a free account at http://www.photobucket.com and upload your photos there. Then simply copy and paste the [IMG] code from beneath your pictures (will appear as you mouse over them in your main album) into your post on here.

    Removing the coil packs provided a lot more working space when I did my plugs. Granted, from the top you are basically working blind, but I was able to reach the back plug without any real issues after the headers were installed.

    I had macs and didnt have a big problem with them. I used a normal plug socket that has the 6 piont end on it and had to remove the coil packs.. I used a combination wrench and going back and fourth between the ends till it was loose then used the socket itself to unthread the plug the rest of the way. I now have hooker long tubes and still do it the same way.

    im new to LS1 and i want to open a new thread....oh guys also I have MAC headers with MAC exhaust and everytime i take it off the line the exhaust hits the bottom of the chassis do you guys know if there are available and transmount that will reduce the flex of the motor moving? also will the knock sensors feel this and retard the computer? I would also like to know if you can get them taken out completely?

    Yes you can get solid motor mounts. Yes banging may trigger the knock sensors.

    if you are still having issues getting that plug....remove the valve cover.......it is 100x easier without the valvecover on.
