How strong is stock Mopar vs Csb?

stock gen3 hemi block will take 1500hp. start with that and save the trouble of finding heads for an la engine that do t touch the stock gen3 truck head eagles.
add a stock 6.1 crank good rods and pistons and main n head studs. you got my engine pretty much and im after 1500hp with a turbo. ill be running this summer i hope.
