So Friday I was able to take the Blazer for a longer drive, ~15 miles one way. Back roads are great at seeing how the suspension works over bumps, pot holes, and wash boarding. Nothing but smooth driving. The snow made it a little bit of a challenge on the way back as the 33×12.5×15 BF Goodrich Radial Mud/Terrain tires are just too wide and aggressive to get any bite on snow covered asphalt.
I did notice that the speedometer is noticeably off. I am assuming that the gear ratio is left unchanged and since the original tires for this truck were H78-15B which had around a 27.8″ outside diameter, the speedometer is off by ~20%. This was using the information on the following websites:

My next task before I actually put this truck on the road is to patch the hole in the bed floor which at this point in time will just include some silicon sealer and sheet metal screws. I will also have to get the exhaust so it exits out behind the rear wheels to pass an inspection. I am not sure if I am going to slap on the headers just yet as the temps outside have been quite frigged and I will need the cooperation of the weather to get it done. Time will tell.
