I have the V8 but speaking for MSD brand, I recently bought MSD wires, best I've ever used! Had fully adjustable boots even though they appear straight only. Nice quality wires inside and out. I also have the cap and rotor which seem well made with the brass terminals as opposed to the zinc colored Motorcraft version.
The only complaint I have is the MSD coil I had bought barely made it a year, but I noticed there seemed to be less pep when going back to a cheapo coil afterwards. So maybe another MSD coil in my future to make double sure.
