lorne #1748

For what its worth, I've NO problem with either #7 or #8.

I bought a Craftsman plug socket with the swivel on it, and using a short extension it all follows easily down the hole, leaving the end of the extension just above flush with the cam cover (when seated fully over the plug) where an additional swivel may be installed. Or, depending on the length of the extension, swivel-head ratchet easily accesses it, no problem!

Maybe its all relative. After changing plugs on my LT1 Vette, changing the #8 on the LT5 is nothing in comparison!
