These fit perfectly on my 1979 Corvette stingray coup and all the wires were plenty long enough. The car runs much smoother and has more noticeable power on acceleration. Excellent product.These are too short to run under the exhaust in tbe oem wire tracks.This set fit perfectly on Ford 351W with Holley hyperspark distributor. This is on an inboard ski boat. All of the wires reached. It does come with a coil wire. THE COIL WIRE IS MALE ON ONE END AND FEMALE ON THE OTHER. This works well with a standard coil. However, the coil I am using (from Holley) has a male end so I had to modify the coil wire contained in this set so that it would be female on both ends. All of the wires in this kit are female on both ends. This kit also came with a neat plastic ring numbering kit to number each wire. Seem to be of high quality.The wires are in decent condition but they are very obviously used. They came in a taped up MSD box with grease all over them and are showing signs of wear. Some of the letters on the wires are even rubbed off.The wires are of good quality however the coil wire was missing.Works fine, they are on the edge of being too short to be called under header wires though for my 400.Great length! Follow the instructions for terminating, and use extra silicone grease to help fit the boots on them and you'll be happy!GREAT DEAL!!Shipping was real fast and these wires on my 87 Firebird GTA look great and made a noticable difference.Thanks alot and I will be buy from you again
