Sarcasm detector, that's a real good invention.

It appears this plug is highly recommended for stock builds and iron heads. What about a mild cam and eddy aluminum heads?  :scratchchin:

Edelbrock recommended Champion RC12YC for the E-Street alum. heads, so I went with those.

  Mine is a 440 with steel heads and unknown compression and old Champion J13Y at the moment and I am sure I will have to update the plugs.


  Thanks  Ron for posting the links :2thumbs:

Actually....Troy posted the link.  ;) I'm sure i responded in some of them though  :scratchchin: (haven't read  through them)

The XR5 is a great plug for iron heads and pump gas compression (9-10:1) but if I remember correctly you're working on a high compression 440 correct ?

That being the case you would want a colder plug (Heat Range) and the "correct plug" depends largely on your static compression.  :yesnod:

MEMORY LOSS SUCKS ,trust me on that..  I am going to try to get a view of the piston through the plug hole to maybe get an idea of what I have Thanx.
