NGK Plugs
Rather than hijacking this post:
http://forums.maxperformanceinc.com/...d.php?t=827970 I thought it would be better to start another one. Specifically I have a '69 428 with 6X-4 heads that someone one else "built". It seems to sound like like "68" cam and the heads have not been re-worked. Anyway I need to get rid of the horrid E3 plugs and wondered what number NGK plug would be suitable. Iridium would be silly for this engine but then here are G-power and V-power NGK's and what number plugs that would be similar to an AC-44 , AC-43 and AC-44. (The E-3's look terrible, contacts worn away, hard to tell rich/lean, hot/cold.  Thanks for the help.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
