Hi everyone. I'm new here so bare with me if this topic has already been discussed. I have a 68 GMC Stepside that came with the 250 I-6 with the 3 on the tree. In the near future I am going to swap out that engine and trans for a SBC or BB but I'm not sure if the stock rear axle can handle the torque. So, my question is: What newer production vehicle with rear disc brakes will allow me to take it's axle and put it in my GMC? Thanks in advance.
