'48 Chevy upgrade ???'s

Let me say from the gitgo, I have never installed a complete brake system so I am in need of a lot of help. I have installed M ll IFS on my Gr8 '48 bow tie. She will have a 250ci straight six power plant. I have the chassis cleaned and painted and ready to plumb the brake system. Must I use a Ford power steering pump or can I use the Chevy pump? I know the pumps put out different PSI but will the proportioning valve take care of the pressure difference? Out back will be a '75 Camaro 10 bolt 8.50" with drums, I Want to get a suspended pedal/master cylinder and vaccum booster setup from a salvage yard (rebuildable), What is the best unit to look for? I don't foresee any problems with it, but I must ask to be sure. Is there anything I should be aware of?

Thanks Al

A lot of rodders find that they do not need the Power steering on their rods ... with the Pinto/Mustang II front ends ... and they just use a manual rack. The Chevy PS pump on a Ford PS rack is way too touchy for me ... some rodders trim the spring in the pump and others use a Ford PS pump. There are companies who make a PS pressure reducer ( adjustable ) ... but I have NOT used one ( I prefer manual steering myself ) .

I would look at Malibu or S10 for a swinging pedal and cylinder. Try to get it all ...

Just my nickel ...

I have pretty much the same setup. Mustang II front and 10 bolt w/drums rear on my '53. If you go with a power rack you can use the GM pump if you install a pressure reducer spring (available from Borgenson for about $20) to reduce the pressure. The proportioning valve will NOT do that job.

I used a swinging peddle from an Olds 442 and a power booster and dual master cylinder from an 85 Mustang GT to complete the braking system. This combination seems to work very well.

All that said, with a little 6 up front you really don't need power steering anyway.

Good luck.
