My problem is with the steering in my 72 Mach 1 w/351c and FMX transmission.

When running above 60 miles per hour the car starts to wander side to side and I am constantly correcting it.  As I increase the speed it gets worse.  I had this problem in my 2 67's that I had.  I have heard if you put a proportional valve in line on the pressure side that you can adjust the fluid flow to help eliminate this problem.  If this is the fix does anyone make a kit or does anyone know the parts that I would need?

If the above is not the solution all ideas are welcome.

Ron...

The power steering adjustment valve you mention is from Heidt's Hot Rod Shop. An installation of one was performed in the November 2005 issue. This adjustable valve allows you to control the amount of power steering fluid pressure in the system, which allows you to reduce the assist, giving you more road feel. This may reduce or eliminate your steering sensitivy and wander issues, but I suggest you get a proper alignment or the front suspension inspected first. Often road wander is caused by incorrect alignment specs (people using old figures for bias ply tires) or worn suspension parts.

Good luck with the fix...

Thanks for the tip I bought the car as a turnkey so I am not sure who did the alignment.
