Would it be a ss raceco?
Dave Richardson and I pulled off that feat at the 1985 Baja 1000 and almost beat the bikes too. We also finished 2nd overall at the Mint 400 and the Frontier 500 with the same car that year which maybe had 90HP. Got to love the single seater as it was just you and the car as if you had a problem you had to fix it yourself. In my 34 years 1985 was our best year in my book as many of those races we had 60 to 80 cars in our class alone. Thinking about building a new Silver Bullet for class 10 and give the boys a shot at a buggy in 2015.
Ford Rough Riders.....For me, one of the great times in off road racing.
