Is there any reason to index your spark pkugs or is anyone doing it to our motors?

I know everyone use to do it on the old SBC, for more equal combustion.

old school, yeah.

haven't heard or seen any reason why to do it on these engines.

I did some more reading about it on LS1tech and there are a lot of guys that say it is definetly worth it but a pain to do. Especially on the f-bodies and camaros.

I'm going to do it when I put my new heads on.

How would you do that? I would think that the position of the electrode would be dependent on how the threads were indexed to the electrode.

There are kits for this, that have washers with different thicknesss to get it perfect.



I found this link on LS1tech.com

I USED TO INDEX THE SPARK PLUGS ON MY DRAG CAR... BUT UNLESS YOUR MAKING OBSCENE AMOUNTS OF POWER OR HAVE A PROBLEM WITH MISFIRES WHERE YOU WOULD NEED THE CHARGE COMING STRAIGHT INTO THE ELECTRODE, I WOULDNT BOTHER... YOU WILL NOT EVEN GET IN ANY WAY A MEASURABLE INCREASE

Yeah in the day I used to do it. Never felt or measured one iota of difference but it felt cool
