Hello everyone a friend of mine recently aquired a pulling tractor. We are not sure what it is or what it is worth? Wondering if anyone can help us out. Motor is a big block cheverlot, 231x34 tire on back and there cut, not sure on the year. Wheel base 12 ft., turbo 400 tansmission. Driver sits between rear tires, fully caged. Rear brakes, thinks may be an unlimited class tractor. Sides of the tractor say 911 and it is red in color? I know that it may be hard to help me out with out seeing it but any help would be greatly appreciated.
