Steering Box Ratio

I'm finishing up my suspension, ending with the steering box, the stock ratio being 24:1. In looking at parts, however, I find that I have a couple of options; 20:1 or 16:1.

Which would be best for a well-handling street driven car?

I already have the Firm Feel fast ratio pitman and idler arms, polygraphite PST rebuild kit, and Addco sway bar.

do you have the quick ratio long pitman and idler arm installed in the car? I don’t think they offer a set for 66-older A-bodies. The only application listed on the FF website is: Headers that DO fit: Schumacher: A bodies W/Tri-Y and 440 (High Deck) ** it doesn’t say 60-66 vs 67-76 A-body. But the Pitman & Idler stud points downward. So you’ll need a 73-76 centerlink or fabricate a new 60-66 centerlink**

The ones I’m familiar with are made for 66-72 B-bodies and E-bodies. They can be made to fit 68-76 A-bodies in certain exhaust situations with careful head pipe fabrication and careful geometry measuring with a special bumpsteer guage.

Anyway… Do Not run quick ratio arm AND 16:1. That will give you overall 12.7:1 manual steering. That is too much for manual steering
