sparkplugs and wires

Can’t lose with NGK. Wires your call, but keep high heat in mind. Might even invest in heat socks for the ends.

...

Motorcraft here too.

Autolite AP25 Platinum is OEM. Probably out last the coach.

I've never been disappointed by Motorcraft parts. The originals last a long time and the vehicle is falling apart before the replacements go bad...

When it comes to vehicle electric items I've found OEM is the best.

MSW (Magnetic Suppression Wiring) wiring and Bosh fine wire platinum plugs, longevity and performance.

I concur completely. AC Delco for GM, Motorcraft for Ford. Every time.

my autozone did not have the motorcraft sparkplugs in stock

but i did get a set of Autolite XP25 Iridium plugs

thanks for all the help

For a 460 or a 454 engine of that vintage I would get the Taylor 10.4 mm wires they are made to withstand high heat produced by both of those engines. They come with a FG sox that fits over each spark plug. If you start your engine at night and look closely at the wires you are likely to see small arcs for the wires to the engine block(ground). These thinner wires(8mm or less) will break down after a while from the high heat. I would just get any of the majors brands of spark plugs. Are you showing any codes yet from the backfires?
