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**[/QUOTE
Yes, I have the aforementioned fast ratio idler and pitman arms from Firm Feel, as well as the '65-'66 V8 center link. I'll be using stock 340 exhaust manifolds so I won't run into header clearance problems.
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
This is more what I was looking for, because part of me is thinking that the fast ratio idler and pitman arms, combined with a fast ratio steering box would be too much to manage, especially when the car is going from a dead stop or moving at a slow speed.
Thus, I think that, with my particular combination of parts, I'm going to be happier with the 20:1 ratio.
