I never reported back on the grinding sound under hard acceleration. I can't say exactly what the culprit was, but it went away with the motor swap. The motor mounts were toast and I replaced them with polyurethane, and all the braces between the motor mounts and bell housing dust cover were loose / missing hardware. Everything went back together with new hardware and it hasn't made a noise since.
