Default 00ls1 01lq4 combo questions

Im new in the world of rebuilding motors. A year ago I replaced my ls1 with a 0 lq4. Swaped over the intake, front drives, and oil pan everything I could find to do I did. I put about 6k on the 6.0 and lost oil pressure. Shortly after a knock started. Yesterday I finished pulling the motor and found that the #16 rod bearing was spun. The cranks more than likely trash but im wondering what I can do on a budget to make ends meet and still have a powerful reliable engine. As far as I know the ls1 crank will work in a 6.0l. The pistons in the 6.0 are good. Will the ls1 rods work with the ls1 crank and 6.0 pistons?? Also what kind of oil systems are you all using to keep from depriving the front of the motor oil. Im looking for ideas and any info that can help me get this car back together. Thanks

#1 rod bearing was in pieces and #6 was starting to spin. I plastic gauged the motor top to bottom. I don't know if the 6.0l cranks are designed to turn as many rpms as the ls1 cranks. Id also like to go back to 10.5 compression I had with the ls1 but don't know how much the 6.0 blocks can be decked and what type of head gaskets to use.

The 5.7 crank has the same stroke but would need a rebalance to work with
the heavier 6.0 pistons
