    p.s.conversion
    « on: November 30, 2005 - 12:06:18 AM »
    My '70 challenger has the 24:1 manual steering. Ok on the road, but wouldn't want to whip a U-turn in it.
    Besides adding the double pulley, steering box, and pump reservoir...what else is needed?
    Is the steering "shaft" etc ok.
    Is it possibke to do this switch on a 440 with stock exhaust manifolds without pulling them?
    Would you recommend the swap and if so to what type (mopar or aftermarket). Seems like I seen an ad for a quickor 16:1 manual conversion also.
    Has anyone done this that could give some advice :worshippy

    a quicker ratio manual will generally be harder to steering
     the steering shaft is a different length , it is relatively easy to go from power to manual as ther is an adapter to lengthen the shaft , you really need a shorter steering shaft to got to power , if you decide to do this Firm Feel seems to make excellent steering boxes
     personally I prefer manual

    I think that you will only need the manual gearbox(can get from steer & gear, firm feel, or flaming river) and a steering column extension. You might want to change your steering wheel to a bigger diameter one for ease of turning.

    Now that I've had the car for more than a few days (which was the case for my initial post in Nov.)
    I'm fine with the manual steering.
    That said, what's the best way to reduce the excess amount of freeplay?
    I can literally turn the wheel back and forth in a 6'' arc without providing any steering input .
    Rebuild mine, replace, adjust ?

    see if the coupler has play between it & the steering shaft , often the shoes are inserted into the coupler 90* off & this causes a lot of play in th esteering
     also there is a Nut & screw on the top of the steering box , with the steering centered loosen the nut & tighten the  screw to remove play inside the steering box

    Chevyconvert,  I just saw your post and have converted a couple of bigblocks to Power steering and brakes. The last one a 440-6 Cuda, The owner was VERY HAPPY. You were right about needing the pump and brackets and a double pulley, and steering Box ( a rebuilt box can be bought from AutoZone auto parts (www.autozone.com) for about $135. If you need a core send back any junk yard PS box.  You also need the Steering shaft coupler, that has a smaller splined hole, pitman arm, hoses.   On most of my conversions, I was able to push the long steering shaft into itself to shorten it. try tapping it in and I wouldn't be surprised if yours goes in too.  Save your stuff with the car, for the next owner that that thinks he wants manual steering again.

    Thanks for the info Rob, I'll hold on to it.
    At the moment I'm elbow deep in carbs sorting out a problem though. :biggrin:

    My car came with some parts that the guy had collected to convert the steering including the double pulley and a reservoir with a finned cooler on it. The finned cooler unit is supposedly correct for a 440-6
    car in '70...anyone know about these? :dunno:

    At this point I'm gonna try and remove some of the slop and get a little exercise while driving. :thumbsup:

    You'll hate manual steering if you ever put a TUFF wheel on it. I have a small 13.5" Grant wheel and put in a tilt column from a floor shifted Cordoba. It looks like a factory option for a Challenger with a cruise control switch on the end. I hated the angle of the stock column and the full size of the HUGE e-body steering wheels, and I didn't like it being that close to my legs. The big wheels also amplify any play in the steering.

    To jump off topic, that you started, try covering the front and rear carbs of the 6-pack with heavy saran wrap and tell me what happens.
