I may hold the record for the earliest (and my only, thank God) spin back in 2005, I think.
It was the first time I put Nitro in my early Olds, and even though it was only 20%, it caught me by suprise when I pulled away from the push truck.
I was running a spool rear end at the time, and the Olds had maximum torque at 3500 rpm.
First the rear end swung to the right, and when I lifted, it came back straight and kept on going around for what had to be the slowest spin in History.
I remember thinking "so this is what it's like"........). I got a great view of all the mountains and the starting line and my push truck going by..................
There is a video of it someplace on the internet titled "Studebaker gets a little loose..."
Hell, I was going so slow that my sphincter never even puckered................. Bob
