I have a running video available. 1984 Chevrolet K20 Silverado 4x4 is a former 6.2L diesel truck currently has a very good running 454 (1987 engine according to PO,haven't  checked the engine # to verify) installed by the previous owner with a brand new new exhaust system from the manifolds back. The mileage of 113,453 is believed to be original to the chassis as the truck quit running and the original owner left it in the barn for years until the last owner talked the family into selling to him. He had a trusted mechanic do the initial basic conversion to get it to run and drive but he didn't buy the correct brackets (left cable disconnected) for the 700r4 TV cable to work with the Edelbrock (manual choke) carb , so it's no wonder it didn't shift right. I have not driven it more than in and out my driveway. I was going to build this truck into what you see on the last pic as it's a factory black truck and super solid body and frame wise. I WOULD NOT consider this a driver until all the details are sorted. Plan on trailering or transporting it to your location. I don't see myself finding the time to finish anytime soon so my square body dreams could be your reality. Thanks for looking.
