I have several 6.2 GM diesel engines out of CUCV trucks for sale. One is a new military rebuild, one has about 5000 miles on it, one has about 100,000 miles on it, and another is a good core. Aslo have several low mileage HD military radiators. one GM 6.5 turbo setup, and one Banks turbo setup. Flywheels, flexplates, etc..... Anyone doubting the ability for these engines to make good power, I have a built 6.2 that puts out about 300hp and gets 20 mpg. It has penisular pistons, custom Banks turbo setup running high boost, custom injector pump, advanced cam drive gears, ported heads, seriously blueprinted, rods and crank lightened and polished then shot peened and nitrited. These are the lightest diesels made, parts are cheap from surplus, and I think people are missing out on a great engine. I am running 5.87 gears with a eaton gear splitter/OD and a cummins NV4500 with OD behind that. Power is not an issue especially with all of the gearing. Am doing a ground up rebuild of my truck and can't wait to get it all back together.
