2wd same as 4wd power steering pump?

Yes, just make sure they are the same design. i believe 1980 and earlier used the flare seat lines and 1981 and later used the O-ring lines.

Are they the same 6cyl. vs. 8cyl.?
The only difference is going to be the clocking on the bracket, and also the line configuration i spoke of. There also is the hydro boost style with no resevoir on the pump but those aren't as common to find.
No they aren't..
A P/S pump off a 4.3 VEE six might fit a small block,I've never tried one,but they do share a lot of parts --but the straight sixes use a pump thats nearly identical,but the pulley wont line up with a small blocks pulley setup(not sure if its just the pulley itself,or if its the pump shaft that is longer)..
I never bothered to see exactly why--I was too PO'd after putting a like new "spare" P/S pump from my 250 six onto a 305 motor,and all was well until the fan belt didn't line up!
You can swap out the "bung" fitting the pressure hose scews into,if the pumps fitting is different than your original..
You can swap the "resivoiur" from one pump to the other..thats what I had to do--my 305's pump had a hole poked in the resivoiur,and after I found out my other pump wouldn't fit,I swapped the resivoiur from it onto the original V8 one..I think the hydroboost pump is the same guts,only the resivoiur is different,AFAIK...never had to mess with my diesels P/S pump--hope I never have too either..

I don't mean to steal the thread, I just had a little question about the different pumps.
So the pump itself won't work from a 250 inline to a 350? But the reservoir will swap over?

Same pump just possibly different pulley.

Could the pullies be swapped? Are the pulley shafts the same diameter?
The shaft's are the same diameter 3/4" IIRC.

Its usually a pain to swap reservoirs without pulling the pulley ,if its pressed on you need a puller, only takes a bolt with a nut and washer to re-install, I have used car pumps on trucks many times.

? Hydroboost brakes pump different or not?
I have had no way to check personally, but a friend of mine, having unsuccesfully tried to swap an hydroboost brake system from an M1008 diesel on a gas K5, keep telling me that the pump of the Hydro-equipped trucks have higher volume (or pressure?) pumps than the others.

My 93 k3500 has the hydroboost setup and 2 of the high-pressure hoses have leaked so that makes me think the pressure is pretty high because I almost never have had hoses leak on my older rigs.

I have 69 c-10 with a smal block My pulley s dont match. My power steering pulley is about a 1/4" short.
