I don't think the motoer that came with my Delta 14" BS is pulling its
weight/doing the job.

I recall a friend (now out of touch) replaced his BS motor with a 2HP
motor and, subsequently, swore by it and the improvement. He made all
manner of intricate carvings with that saw and it always appeared to
cut as if going through butter.

Has anyone replaced the stock motor on this saw? If so, with what
(specifics, please) and with what results?
