oil pump alighnment

[skeet]

Do not use sealer between the oil pump and block. Also the alignment is not critical, the only pump that needs alignment is the dry sump on the ls7.

it may not be critical to you but any decent builder needs to feeler gauge the pump/crank sides in the spots across from each other, specially on a aftermarket pump. this way you know its centered in its bore thus not leaving any guess work if something was to go wrong with the pump. specially if you dont pull the bolts up equally
