Looking good. I did a 51 GMC over 30 years ago that now has around 300,000 miles on it. It wore out the 472, which was rebuilt once, and the 500 in it now has close to 100k on it. It's stock with the a/c compressor still mounted into the front of the intake manifold. That big booster will give you super brakes but one suggestion I have is to fab a really strong crossmember to tie the front of the frame rails together. Without one the power steering will flex the front of the left rail due to the weight of the engine and probably wider tires. The torque is amazing.
