A lot of information on the web about converting a military 302 to civilian use. If you plan to put it into a civilian truck in summary: You will need a 270 6-bolt flywheel and matching starter and clutch. Can use the front dampener but need to move the radiator on the front side of the radiator support, or use a 270 front dampener and leave the radiator in place. Grind off the protrusion (boss) on the block just ahead of where the starter is located. 270 distributor will work. Drill out the oil dipstick hole. It is a two step drill size. You will need to find a 228-248-270 oil pan and matching oil pump. Generator bracket - a standard OEM bracket will bolt into place just fine. Water p8mps from a 270 even 248 will work...not sure about 228 but my guess is that it will work. You can cut out the boss for the fuel pump or leave it alone and use an electric fuel pump and put a dummy OEM fuel pump where it should be located if you want an original look. The head and manifolds can be left alone. Change out the front motor mount to meet civilian truck front cross member. This is most but not all of the easy improvements you need to convert it.
