I have my truck down to the frame and drivetrain. After checking the engine #s, my 283 was out of a '66 chevelle. Since the radiator apears to be factory with appropriate mounts, etc I assume the original engine was a six. From the Chevrolet price and facts book printed Oct 1962, there were 3 engine options listed on several pages for the K20; 235, 261 and 283. There seems to be some issue of dispute about the 261 available in '63. Can anyone help me to determine what engine would have been the original for complete restoration?
