spark plugs
The plugs were black and sooty. Bosch platinum recommended for a 400 in a 73 charger. These were not but 2 or 3 months old when taken out. As for highway use i try to avoid interstate. Most of my driving is around town. It screams on highway so i guess it would probably run hot, but don't know for sure.
