I wonder if others have a book where they can record the parts they have on their truck. I have done so many mods that I am losing track of which year and model each part came from. Internally, my rods, pistons, rings, crank, and even the block and head are all from diff years. I have chebby valves, alternator from a 94 Taurus, hydroboost and master from a 2011 superduty, trans from a 91 with a 351, pwr. steering pump from a 74 LTD with a 460, starter from a 91 F250, rear calipers from a 76 caddy, etc, etc.
