gmcbaseball, I also have a 54 GMC 1/2-ton with a longbed that I am restoring. My original 248 had been removed before I bought it and a 261 Chevy engine was in its place. It is much cheaper to rebuild the chevy engines than the GMC engines by the way. If you have any questions about your 54 feel free to ask me as I am into the restoration of mine as well. You can see some pics of my project at:
