who makes a decent fitting set of stock type black spark plug wires? and where to buy them? for 1970 350/stock distributor

 

I like the Taylor Spiro-Wound wires. Good product for a reasonable price.

 

You're pretty much on your own to buy a set that you can tailor-fit - the pre-made sets are ok but not really 'fit' to size out of the box. Many good spiral core brand choices though - MSD, Taylor, Accel all available in black I believe (but they will have their brand logo markings on them) - minimum size you might want to go is 8mm. Be sure whatever set you buy includes a coil wire - apparently not all do. Also be sure to differentiate between HEI and non-HEI to ensure you get the correct coil ends.

 

The stock points wiring is 7mm.
