Adding Power Steering 1968, 327 / 350 hp crank pulley

[Gary J.]

I am anticipating adding power steering to my 327, 350 hp 1968. The crankshaft pulley is a two groove currently, what is the proper routing of the power steering belt with this application? Do I need to change the pulley to a 3 groove, or does the same belt run both the water pump and then through the power steering in a 2 groove set up? Also, Which is correct as far as the cap on the power steering pump, it looks like from my research it is Metal through 1968, but then in 1969 it becomes Plastic. The car has its AIR installed as well.

Thank you for your experience and knowledge

Robert, correct in the AIM N40, A 6. The 3 groove on top and 2 groove on crank pulley, the belt drives both power steering and the water pump on the lower pulley. Thanks for your help just spaced out looking at the AIM.
