What spark plugs are we using

[nicanor]

Now that I'm putting the engine back in the car tomorrow, what kind of spark plugs are the best for the 383. We're using the Holley 770 Street Avenger, no headers but a very aggressive cam.

Thanks,
Barry

Autolite 85's used to rock, now they come from China and suck. If you can score some old stock that came from the USA, then grab them and run 'em.

NGK seems to be the trick of the week. I don't know the number right off. Parts store should be able to help.

Indexing is worth the time if you have the time to spare.
