Can anyone tell me what I need to convert my 1971 F-100 2 wheel drive from standard brakes to power brakes? It has drum brakes right now and I plan on converting to disk brakes later but I want to get the power brakes outta the way first. Please help.

you need to get just about everything that goes with the braking system but the most important is the perportioning vale you will also need a different one when you change to disc brakes also

What do you mean by everything? Brake master cylender, Power booster, Perportining valve, New lines? Did I forget anything? Can I still use the drums that are on it? I dont have power steering eather. Do I need to convert to power steering before converting the brakes? Please be as detailed as possible. Im not much of a grease monkey.

To go to power, you'll need the booster, pedal link, vacuum hose and the vacuum check valve.
The master Cyl should bolt right up, but you might have to adjust the pushrod that comes out of the booster so it does not hold the M/C from returning fully, or leave too much of a gap.
There is no such thing as a "proportioning valve" on most any vehicle with a dual-split brake system. The "valve" with four lines to it and a wire or two is a JUNCTION BLOCK with an itegral IMBALANCE SWITCH, nothing more. The proportioning aspects are designed into the master cylinder bore and the wheel cylinder (caliper piston) sizes.
