Hi Gordon, a 8.3 runs the same rpms as the 6v, and was informed has more torque. My gear ratios are the same as the 90s coaches with the same engine trans combo, 5:29. I will be using the side rad that came with the engine. Should be close to the same cost as a rebuild on a DD. When its finished. Ill be posting pics and info as I go.
