This is a GM ls1 truck sump,

This is a GM ls1 truck sump, it can be used for the conversion but will hang well below the cross member thus it will botom out and get smashed. They can be modified ( cut n shut ) I chose to use a castle main rod shop sump because they are well made, the downside is that a CRS sump needs a remote filter. CAE have told me that thier sumps have the filter intergrated into the side like a ome sump.
