So with the block removed now is it level? I know that feeling. I was doing my rat rod and was in a rush to get the shock brackets built and install the shocks. I made all my measurements with the frame on the ground, when i jacked up the frame, i have a suicide suspension and put jack stand there. Went to install the shocks, found my shock towers were 3" to high, so i cut everything apart, welded back together, installed shocks, set truck on ground. Shocks bottomed out. Realized after looking at what i did, that i measured with the truck sitting on the ground, not in the air. Had to readd the 3"........silly me.
