How strong is stock Mopar vs Csb?

I might be wrong but all the 350same have four bolt mains, where all small block mopars had a 2 bolt main unless you get a 340 x block which had 4 bolt mains. But a member here was shooting for 1500 on a two bolt set up just on a 360. He had the block line honed on the crank maybe even the cam so everything was true, stud the mains, heads and for that power need forced induction either turbo or turbos or supercharger. Forged crank, rod, and pistons, good flowing heads aftermarket (indy or edelbrock). Turbos are easier on the rotating assembly since it's a gradual increase of power. Have to modify the oiling system there's a good thread on that. Course first of all have the block sonic tested and magnafluxed just to make sure the block is in good shape.
