Locking up is most likely caused by the new bearings. Did you verify bearing were the proper size. Standard or over size?. You can always disconnect the transmission by removing 4 bolts on flywheel and inspecting it, without having to remove the engine and try to rotate engine from the crank shaft pulley but honestly I think the engine is shot. You should've checked oil pressure before and after bearing replacement
