is there anyone that builds a fast ratio power steering unit or do i just need to order a different gear from steer and gear. is the firm feel box fast ratio or just stiffer.
There is no such thing as a faster ratio power steering box. The T/A fast ratio steering box is the same ratio as the one on your car now. It just has the internal stops changed so that some idiot won't jam the steering wheel cranked to one side, move the car, and chew up the tires.
Just don't do that.
The fast ratio is acheived by just adding the longer arm and corresponding C-body idler. That makes a 12.7
overall ratio. In comparison most new sports cars are around 14:1. The faster overall ratio is nice on an autox course since it's tight and you make extremely quick turns.
I don't have a quick ratio arm. There's a lot of A-body Autox guys that don't use them. They would like to, but they are avoiding the hassle and they are concentrating on other parts of the suspension. And the biggest reason is they are not header friendly in an A-body. Not really stock exhaust manifold friendly either. It would hit exhaust pipe I have with 340 cast manifolds. I know someone that has got the long arm to work with 340 manifolds but they were really tricky and IIRC, had some generous clearance dings/pinches.
How much room do you have now between the end of the pitman an the exhaust pipe? If you have to modify your exhaust pipe the price of this swap just went up $50-80.
The longer pitman will increase the leverage acting on the steering wheel and make the steering effort increase somewhat. So will a smaller diameter Grant steering wheel.
Your car doen't "feel tight" for numerous reasons. Tires, worn steering box, alignment, springs, and shocks are a few reasons.
