Review on ACCEL 4040 Spark Plug Wire Set 8mm SUPER STOCK GRAPHITE UNI, Yellow: Performance-boosting Ignition Wires for Enhanced Engine Efficiency by John Camelio

They will cope with their task, good quality cables, but for some engines they are a little short. I have a Cadillac 472 in my Fleetwood, the wires were almost too short to fit the way I wanted but I was able to get them to work, they would probably work better for a small block. Also, they tend to slip off the spark plugs so I have to slide them back from time to time to reinstall them, but that may only be because the leads are a bit short.
