    I never noticed this before on OLM site but they call T651 'cold finish' & T6511 'extruded'. T651 goes for 69$/ft. T6511 goes for 44 $/ft. Since I'm after a 3" dia slug & will turn it down to 2.8"-ish is one alloy more referable over the other? (Crankcase related parts).

    I found the tempering properties here, but they don't really mention cold, finish, or extruded.
