Starting to put the engine back together ,,,noticed the front pulley is locked down,,,,on this engine the engine is not locked down at TDC ,,,,,it is lock down at 150 degrees from TDC,,,,the reason is so no damage to valves can happen while performing any work on it,,,,you can notice the cam lobes are not facing in the normal  up position or point at each other,,,,cam lobe on one bank is facing down and side ways,,,,it’s very different timing this engine,,,,,also with the intake and exhaust ports are in  different positions.,,,,,this is not a normal engine to work on to say the least.
