12.7 60 series no start

[eggtrucks]

Have a 12.7 Detroit series 60 DDEC IV that had the bull gear bearing go out. Stripped out air compressor gear and chipped teeth on crank gear. Engine would still start and run, but no throttle due to fuel pump being driven off air compressor. Cam gear wasn't affected and stayed in time. Replaced bull gear and crank gear, timed all gears per manual spec.
After everything is assembled engine doesn't start or fire. It produces insane copious amounts of thick white smoke while cranking. Everyone is saying its a timing issue, however i double checked everything including pin on cam to verify it wasn't pressed into the cam. replaced srs and trs sensors. tried spare ecm, no change.

Any ideas??
