Mine was back in 1989 at what was called our Gary's Picnic event, basically a heads up anything goes race with £1000 for the winner which was held once a year and made famous by the swedes who came over and won most times with their super fast machines.
Anyhow at the time I was running my 440 '69 Cuda big tyre car with N20, was a stock 440-6 motor apart from a big sft. So I came up against my mate who did the back half on the car with his Opel Manta running 427BBC power + N20, an 8 sec runner but on that night he was chasing a strange on/off misfire, long story, I took the win by .0000 whatever and saw him come by me at the stripe around 30mph faster, I upped the jets to go in the 10's, apparentyl I was told the crowd went mad at that, underdog always supported, that got the swedes a bit worried as my next round opponent came over and asked what I was running, of course I said 9.0's to put some fear into him, I went out to him but will never forget that race and the incredible nights racing that was.
