Technical Pitman arm length - corvair box

I am looking at a 32 chevy low boy style coupe. Has a speedway type 4" dropped I beam front axle and a new corvair steering box. The steering just feels slow/behind. Takes forever to go from center to lock on either side. I'm not sure the pitman arm or the steering arm are the correct dimension. What are you running for pitman arm length for the corvair box?? thanks.

 

So how many turns lock to lock do you have now?

 

I wanna say like 6 turns lock to lock

 

I'm running an original factory Corvair box and pitman arm on my old Austin g***er, and the pitman arm is only 5.5" center on holes. It turns very fast, and not nearly 6 turns lock to lock. I wonder if yours is an aftermarket box with a slower turn ratio than originals?

 

I have to wonder if all the press releases (!) on the Corvair caused the 'slower steering' ratio to be changed, (Factory GM) to keep the oversteering from being 'unruly'.

 

It's got a Jegs box in it. From what I understand there were two ratios originally, but that really doesn't help me.

 

Beside maybe using a longer pitman arm to make less turns,lock to lock; You could instead,use a shorter spindle arm=same thing at getting a faster steering.< I said that ,as aften a few get stuck on,only one way to do things=there are more!

 

If your steering arm is made from flat plate & uses spherical rod end , you could drill a new hole inboard an inch , see if that quickens it up enough . Standard lock to lock corvair box is 5 1/2 turns .

 

I started with a Corvair box in my roadster. I hated it because of the slow steering. I put a 1.5:1 quickener in the steering shaft. Much better, but requires more steering effort.

 

Are there any longer pitman arm choices for the Corvair box ??
I'm in the process of setting up the steering in my 27 .
Seems like it could be quicker .
Stock arm and a aftermarket arm I have are about the same length .
I haven't looked to hard at aftermarket arms yet

 

I have a GM Corvair box reversed in my roadster. It has 5 3/4 turns, I was thinking this is going to be terrible! I went ahead and put it together anyway. With it all hooked up it is now right at 3 3/4 turns lock to lock.
