81 c10 power steering box questions

[k1rodeoboater]

Hey guys I own a 66 c10 and want to swap over to disc in the front and power steering. I know the brakes shouldn't be an issue, but the power steering box on this truck has me scratching my head. The guy who had it said it was originally a diesel, and he swapped it for a 350. However the power steering wasn't run off a pump on the motor, but off of the brake booster. Is this the same power steering pump used on this truck as a normal C10

Other way around. The brake system was a hydoboost, with assist provided by power steering pump pressure. The steering box is the same as on any other truck. The diesel pump would have had slightly different hose connections, usually 1 more return line and/or a remote fill pipe. Pump guts are basically the same.

If you have a vacuum brake booster now use a regular power steering pump. if you have a hydroboost use the pump and lines off a 1 ton or diesel that origianlly was hydraboost equipped. Be sure the hose routing is correct (i.e. pressure to the correct side of the gear and the booster).

Sweet thanks for the info. I've got a vac brake boost I will eventually be installing, so in that case I'll need to get a pump. A pump off of a 350SBC would work fine then right?
