Yes the Mosaleen idler pulley should be considered. I trust JimIII of JDM and he suggests the V-10 water pump pulley is not needed until the s/c pulley is 3.2" or smaller.

I am also considering an electric waterpump, an aluminum driveshaft, and a canton oilpan windage tray. These add HP indirectly by reducing parasitic engine drag.
