WAS WONDERING ABOUT ALL THE BRANDS OF WIRES HAVE THE SUPER STOCK 8M ACCEL WIRE NOW BUT WAS WONDERIN IF THEY COULD BE POSSIBLY LEAKING VOLTAGE AT 7000 RPM WHEN TEMPS RISE UNDER THE HOOD HAVE NO MISSING PROBLEM BUT WAS WONDERING IF THIS IS POSSIBLE

Well i guess it's possible,one way to be sure you're getting all the fire to the plugs is to use solid core wires,then when you're racing you're also jamming radio frequencies.

Be careful with solid core wires because they emit a lot of radio interefernce and will s c r e w with your electronic ignition. MSD states right on their box 'Do not use solid core ignition wire'. If you have an old points type distributor then you would be fine.

one way to fight the leaking problem is to make sure they do not touch each other at all

We blew a motor up last year due to the plug wires leaking. 5 and 7 were touching, and caused it to spin a bearing, break a rod, and destroy everything but the heads and intake. I will now swear by the Iron Eagle heads, we have a flat top piston out of that motor that now has a minature dome it the same shape as the chamber. We had the head checked, replaced a few valves, and it is on the current motor this year!!

I think dirtbuster has it right on the solid wires. Something to be aware of is that there are several well known brands of performance wires with thick silicone insulation which are not spiral wound but carbon/string like OEM. These companies also make the good stuff. Read the package carefully.

As far as the wires touching: Whenever electricity travels through a wire some voltage leaks out, period. When another wire is close it will pick up this induced current. With plug wires this is not much problem as long as the induced current of one doesn't fire at CLOSE to the right time for another cylinder. This can occur in a SBC between #5 and #7. These wires should never run parallel and close. Running parallel gives time for the induced voltasge to build. For years I have bundled other wires except for 5 and 7. These two wires should only cross at 90 degree angles and never be `parallel. They and can even be tie wrapped due to their short distance together. This doesn't look pretty and neat but it works.
