Thanks for the replies. 3.54 is about as high as I can go with the Dana 60. I have not bought my wheels and tires or ordered my rearend yet, but I am ready to do so.. On the front I can run a 16 inch wheel the smallest for the disc brake size I have. I am not locked into a 17 inch for the rear and could order my disc brake size accordingly. Car is mini tubbed to the rails and currently has a 3 inch relocation kit on it. I believe I can run up to a 29 1/2 inch tire without having to do anything to the outer wheel wells. As Cab brought up is there a better tire option that you would suggest? Bias ply, MT ET street or Hoosier. Car will not see wet weather. Thanks again. You guys have given me a lot to think about.
