Best Plugs 70 383?????? - 01/30/11 02:57 PM
I need to put new plugs in my 70 383. It is 30 over 484 cam with KB pistons maybe 9.5 comp with stock 906 heads. It is an auto. with a stall and the orig. 323 gears. The plugs in it are Champion 12's but they are 7-8 years old and are now fuel fouling so it is time for new ones. What are the best for just driving, I don't race it. Thanks Ronnie

I like the Denso plugs.Same as Accel(Denso makes the Accel plugs) and they last.W16P-U is the part number.Get them at Auto Zone.

Autolite 85s or try NGKs.I ran Autolites for 45 years in all the BBs and SBs.Installed NGKs in my aluminum headed 440 with 12.5 pistons 2 years ago and it runs better and idles better.I ran Accels a few times.Never really saw any difference for the cost.Rocky
