70 C10 307 Power Steering Conversion Question (Newbie)

[ChevEE]

I purchase a 1970 C10 with a 307 last week and the previous owner had started to convert to power steering. He had already installed the gear box and made all necessary steering assembly replacements. He told me all that was left was to install the pump, and he provided me with the pump, brackets, and hoses he had already acquired. I was looking through the FAQ's here and found a lot of great information, but there was one thing I can't quite figure out. Is the power steering pump driven off of the crank or the water pump?

I have worked on cars for a long time, but this is my first attempt at a restoration. Any help would be greatly appreciated!

the crank pulley,did it come with a 3 grove pulley or a 1 grove? you will need the 3 grove for power steering

I have a single groove crank pulley. Also, I do not have A/C. I assume I need the triple groove pulley because the outer groove is the one that would line up with the power steering pulley, is that correct?

Thank you. I have been googling belt diagrams and come up with nothing so far. Only problem I see is that my alternator is on the driver's side above where the power steering pump will be. Though out of placement, that shows also that the power steering is driven directly off of the crank with no other accessories.


When replacing the crank pulley, is there anything else that needs to be considered? Thank you guys for the quick replies.
