spark-plug & plug-wires brand?

I have a '82 Dodge Van, 360 V8. It currently has a Mallory
Ignition, Mallory Wires. I don't recall the spark plug brand, but I have used Champion in the past.

What is the best spark plug to use? The local stores have been recommending AC Delco resistive ($1.29). They say the Bosch Platinum ($1.99), won't give any noticeable difference. What about Autolite, Champion..the basic resistive plugs? I notice Autolite has a platinum version.

My Mallory wires have been there for 5 years (my van is not a daily car), I should probably change them. Any recommendations on brand? I have some old Accel wires (custom) lying around for 15 years. I've heard of Autolite wires ($28), Borg Warner Nascar ($41).

With respect to above (wires & plugs), I need something bang-for-buck. Not anything crazy, i.e. shelling out tons of $$ for 3% performance increase.

Thanks for any help.

Champion Champion Truck Autolite
Stock RC12YC 4071 3924

"The stock plug for the Dodge Magnum 318/360 V8s and the 3.9L V6 is the Champion RC12YC so we will use it as an example.
The "YC" means "Projected Nose." Quoting from Champion......
"This gap style projects the spark an additional .060 inch into the combustion chamber for a total projection of 0.210 inch, and providing there is sufficient clearance to valves and pistons, provides the ultimate in performance. Initiating the flame front closer to the center of the combustion chamber has a similar effect to advancing the timing. Therefore, maximum timing may be reduced which helps reduce the chance of detonation and provides superior part throttle response. A second valuable feature of this style is a broader heat range. The core nose is longer, providing a 'hotter' plug at low speed which helps prevent fouling. As engine speed increases, the incoming air/fuel mixture flows across the tip of the core nose, providing charge cooling which effectively reduces heat range at higher engine speeds for increased preignition and detonation protection."

I think I'm leaning toward staying with a Champion RC12YC. Anything else, I'm changing parameters.

"If it ain't broke, don't fix it"

If anyone has some compelling testimony of non-Champion RC12YC plugs, I may try it.

Champion RN-12YC plugs, and a set of Niehoff Gold series wires.
