i watched a video on the orange zl1 69 camaro/black corvette, and they shave the tires down to zero tread and run them like a slick.really?i would think the tech would want some tread for safety reason,the tire must be pretty thin at that point.it really does look like a slick to.and they are running 9s on those.
as for cars,my vote would be 67 fairlane med riser dual quad,or for fun,1969 boss 429 mustang.i think you could get it pretty light and in the low 10s pretty easy at 620 cubes.also had f60 15 from the factory.down side on that is the 735 carb.but hey,super stock 68 cj mustang went 9.56 in legal trim with a 735 factory type carb!actually,a 68 coupe with a max size fe and max ported cj heads may do pretty good if there is no weight minimum.
not a cheap form of racing thats for sure!
