chevy power steering pump vs ford power steering rack

The short answer is yes, but you can add some shims and knock down the pressure to a usable amount. Lots of info on 'how to' with a Google search, not a difficult procedure.

will my chevy power steering pump over power my ford power steering rack was told my power steering pump puts out 1200 psi and the rack will only take 800 psi

The G.M pump is too strong for the Ford rack. I am running the same setup and I took the G.M.pump valve out and added shims to reduce the pressure. I read a how to in an old " Street rodder " mag . I will check around and see if I still have it and let you know. You can also buy a valve from a rod shop which will do the same job . I think they are about 40. bucks .

HI 48 PONCHO : I am running a GM pump from a Box , driving a 94 Buick LeSabre rack ( rear steer )-- Same situation as mentioned above . High press pump driving lower pressure rack . A little too agressive at first , but very light and very quick . Used to it now , but it took a while .You can adjust the press relief valve , as mentioned above , but I have not . Works well -- LATER -- DON -- fleet 51

If you don,t adjust the pressure down to the Mustang specs you will probably blow out the seals in the rack and it will turn real quick and be very light. Road feel will be in your seat and not in the steering wheel.

Reducing the pressure will work but is it right? Unless you know exactly what the units came from your just guessing. I looked in the 87 ford factory manual and they don't give any solid pressure ratings (mustang cougar t bird a few others are covered) but they do say when replacing to go by the code on the pump body as they are pressure specific depending on the model. they also change the steering geometry even between the same models with different options . The latest theory between the gm and ford rack is flow not pressure . Without solid statistic this hole game is a crap shoot that will work in the end but suffer one way or the other. If it were me I'd match the factory pump to the rack it was designed for. Even then there are other factors to consider.

I have run several different valves,shims,etc but after driving they never felt "proper" although these things do help I found the best was just to make brackets for the stock mustang 2 pump and run it with what ever engine I was using for that build and got the "feel" back I was looking for. Just my 2 cents. Yes it is nice to talk normal and share idea's!!
