Hey just look at my sig...I was just wondering what some of u guys were running and what would be the best plugs AND Gap setting for me...
ive been using motorcrafts for years but i was thinking i need something alittle more powerful now...
i got the 9mm wires as u can see, but still running stock distributer and coil for right now...update later on..i do have the msd ignition box thoough.

Hey, looks were in the same boat on this question. I posted the same spark plug question last night. Take a look at my thread as it already has several responses. So far it looks like the Autolite 3924 are the most common for aluminum heads. I'd like to see some more inputs before I decide on which plugs to use...

With a stock ignition...stock plug and stock gap. Simple as that.

Motorcraft plugs are the way to go.

yep, but then i noticed the msd 6al. should be good for a little extra gap, no?

Hey not to steal this thread, but here's some more questions to add...

Anyone ever use Bosch Platinums? I used those in my '88 before i knew much about cars, and it ran like a top. They come pregapped too. Do you guys get your Motorcraft plugs from a dealer?

Everyone I've ever talked to said: Stay with Autolite or MotorCraft, period
