Just curious who built your engine? I know a few racers in Oklahoma. The 950 is the way to go with small carbs , I was going to say try the K&N stub stack(if its ported to clear the air bleeds) if your carb has an air horn . What did your truck weigh?? It runs fast no doubt. I ran a bigger tire than you (I think) , I used the 29.5x11.5 Mickey Thompsons with no tubes. They where kind of big but the truck would hook-up anywhere. I ran a 331 with no tourqe, so I can see traction being a problem for you.
