I was wondering what the best wires and plugs are that i should use in my 1987 350 GTA?

 

I like regular AC plugs and Taylor 8mm Spiral Pro

 

I have Bosch plat+4 in mine.Rapidfires are also good,but I would get platinums because they last longer and I wouldn't want to change them again because thy are a PITA.As far as wires I have SLP's but their disc.TPIS ,and Performance Distibutors also make excellent ones to,the TPIS ones look factory and cost around $50, the Performance Dist.ones are red and cost around $100.I would also change your module,coil,cap,and rotor if you haven't already.

 

Wires are easy, MSD Super Conductors. Lowest resistance wire on the market (less than 50 ohm/foot). I've tested them against other wires and I was amazed how good they are.

Plugs are another thing. You can buy those gimmicky plugs...but what you want is to open up the "flame kernel" as much as possible. I've tried platinums and others, frankly I prefer good old AC Delco. Just grind back the top electrode a bit so you can see half of the center electrode in the insulator. This exposes the spark flame to the combustion chamber better than any "gimmick" plub. If you have a good coil and good wires, gap your plugs a little wider from the stock .035" to .045".

 

For plugs, go with good old A/C delco. Wires, go with taylor 8mm cables.

 

Does AC Delco make only one kind of plug? I'm assuming they make more than one kind, which ones do i want?

 

Regular AC's not rapid fires

 

Whats wrong with the Rapid Fires?

 

Nothing, but I dont see the need to spend the extra Money. I have found that the regular ones wear better with my 6AL box.

 

I have the 6al box, so i'll most likely get the regular rapid fires.

 

The BEST wires are probably Magnacores...but they are EXPEN$IVE.

Whatever plug you buy get platinums, b/c they are a PITA to change.
