STP was big time in the mid 60s, my Dad would take me to some of the big time
drag races at Houston International , Big Daddy Don Garlits and the like.
Anyway, we would get pit passes so we could get a close look at the machines.
It seems every crew would add STP to their engines .
Every high school boy had a STP sticker on his car.
Yeap, STP was the stuff !
