im looking for a good set of plugs to tune my car up a bit for the track. my car pretty much only sees track action now. What should i buy :confused: I have been using plain old GM wires that are highly resistant.
Conductor is wound like a spring on either spiro or heli wires ... solid is a straight piece of wire. Do Not use solids on anything that has a radio (AM/FM) or electronic ignition (HEI) or may be upgraded to performance ignition (MSD). Solid wires create a lotta RFI (static). Do use spiro or heli! Use 90 degree sp boots on virtually any sbc... regardless whether factory or aftermarket exhaust. The custom fit (for your year, make, model) will USUALLY fit OE loom configuration & routing just fine ... BUT if you deviate from OE loom config then you'll be better off with universal fit (you cut to length & you terminate at cap).
Take a look at successful circle track motors ... most don't have looms/dividers. Typical is sleeved Moroso wires ... 5&7 and 6&8 drop from dist & loop under headers ... 1&3 and 2&4 lay right on top of intake and drop over front of heads ... then loop back under headers ... no looms, no dividers. Just hi-grade SLEEVED wires driven by MSD box & coil ... or a chevy HEI in lower classes. No problems either way.
Most major sp wire brands have MANY different grades & designs. In the simplest terms there are kinda cheezy Accel wire paks and beefy, VERY GOOD Accel wire paks. I like universal fit Accel 8.8 mm 300+ ferrospiral Race Wires (either universal or custom 8.8 racewires have 4-digit pn beginning w/ 7). Moroso Ultra 40 is also beefy design ... big$. Any MSD & higher end Crane, Mallory & Taylor are also well-made. I work with a lotta big$ circle track stuff ... at the most, Magnacor & Nology may be an outlier on that radar screen.
