Many, MANY years ago, I was running 13 ohs/teens at Irwindale, the FIRST one, and I wanted a 12 so bad I could taste it.
I had been running thru mufflers, so I decided to see what I could do uncorked.
Turned out, in the other lane was a car I had looked at earlier, a BOSS 9 Mustang, tuned by Earl Wade, an excellent Ford guy.
I left on him, and held him off to the finish line, picked up a timeslip of 12.96, 107, for my first ever 12 second pass, and beat a boss 429 at the same time.... with a 350 powered four speed 57 chevy.
Now, 12s are really slow, get used to a high9/low 10 car, 12s don't impress.
But it sure is a great memory for me, 40+ years later. More so than any of the races I've won.
