What spark plugs to use on my 98 MARK VIII LSC chipped?

[vikingdiesel]

ok, so I took out to see what plugs are in there now, and it seems like the autolite 764's, should I convert to the Motorcraft AWSFA 22C?

IF you can find a place that wont tell you "they dont exist" as most places say.

No need to change brands, you just want to make sure you have "GOOD" plugs in there.
Put 764's back in there and be done with it.

NGK TR55's for NA and NGK TR6's for nitrous or mild blown applications... put an NGK plug next to an Autolite plug and then tell me which one you would prefer to use...

LOL, are they shiny?

A couple of my cars call for NGK's. Damned good plugs. But expensive.

I like NGK and use them in everything else... but I have no hesitations running the motorcraft plugs...

The Autolite/Motorcraft plugs work fine, never said they didn't but I prefer the NGK... The former would be my 2nd choice.

here's a good spark plug http://kalecoauto.com/index.php?main_page=product_info&cPath=2&products_id=5 & don't forget the wires, http://kalecoauto.com/index.php?main_page=product_info&cPath=2&products_id=14. Also, the O pipe will help out with your bottom end.

I installed the autolites today, not really any difference from the previous autolites that were in the car which were the same anyways

I would have expected a 50 horsepower increase myself.

Only if they came with stickers, and you would need two, it's only 25 hp each...
