differences in 68-69 crank pulley to 70 and up crank pulley for Lincoln with crank PS

I finally got around to messing with my March pulleys that I have.  I got a good deal on them and would like to use them.  According to their site, I have to use the 70 and up water pump.  Ok, no big deal..  So I temporarily bolted the Weiand water pump and put on my 3g alternator.  I remove the 68 crank pulley which is the pulley and damper all in one.  Now, I have the Lincoln crank driven PS behind the pulley.  I would like to use this if possible since this is going into a Cobra and space is limited.  I soon found out that a 70 style damper will not fit.  Perhaps I should have known already but I didnt.  As you can see down below, I have a slight issue.  I would like to use the pulleys and I would like to use the crank PS.  I hope this is not a case of having your cake but not being able to eat it.






You can see the damper up against the PS pump. This is no good..




Are there any alternatives to this crank damper?

So what is your issue because I "do not" see it in the pictures? What cobra do you have and have you fit the motor in the car? There are a lot of cobras with 460's in them so this should not be rocket science.

Here is a FFR with a 460 and there is plenty of room. These cars have more room in the engine bay then in the cockpit. The only issue would be the front crossmember but you can usually push the engine back.

If you look at the pictures, you will see the damper up against the crank power steering pump. The damper is just sitting there. The bolt is not on or tightened down which would need to push the damper back to where it needs to be.

As for the room, the picture you used explains my point. If you look at the steering shaft in that cobra, you will see that there is very little room.

Here is a picture of what I have currently. It isnt the best because the heads are removed. This is why I liked the idea of a crank power steering pump.



I will probably sell all the 460 crank pump stuff, sell the March stuff and go with CVF Racing pulleys.

Not Positive as I have never messed with a Crank PS Unit, But I think a Custom Lower Pulley would do the trick and March Could make it. I had Auto Speciality's make me a Custom PS pulley for my 6/71 Blown engine and all my problems went away. PS: Why do you want PS on a Cobra anyway?

J Rupp...

Are you using the "short" water pump that came on those cars OR a later " Tall" pump ??

Years ago, I had the earlier balancer on a 507 in a 69 Mustang and had to use the short pump to make things line up..

I contacted March today and was told that a crank pulley could not be made. I am sure the cost would be so high that it wouldnt even make sense.

As far as why.. When my dad bought the kit, he had it set up with the ps rack & pinion. Also, I don't think I want to deal with steering around with a big block. I have problems with my shoulder and I think not having PS would add to the issues that I already have.

The factory pump was short for 68-69. In those pics, I have a 70's and up Weiand pump.

I have since decided to ditch the crank power steering. My plans are to use a saginaw pump. At this point, I am unsure if I want to go with the Weiand that I currently have (that is new) or go with an electric water pump.

Any thoughts as to which would be better?

The electric pump you can leave it on after you shut the engine off to cool it down

Ok...Thought you had a long pump on there...

I do have a new "short pump" on the shelf if you're interested...

Probably because he wants to drive it. Manual steering is for race cars and it sucks in a street car. Especially one with large front tires.

Probably so with a Heavy Big Block. We had a SB T-Bucket with wire spoked motorcycle runners and it steered fine but, ( don't try to spool it though LoL ) was only about 1,500 lbs. Didn't know he had a bad shoulder either, and the rackNpinion crossed my mind after I posted. The reason I got off somewhat cheap, if you consider 75 to 100 dollars cheap, is I had the pulley on the Saginaw pump cut with about at least a 1/2" more setback to match the groove in my crank pulley.

I've had two surgeries on my left shoulder from a torn rotator cuff. It still isn't correct. It pops frequently.. My dad passed down to me a 36 Mercedes 500k. It is built with a Ford 2.8 v6. It has manual steering and it sucks.. I have contemplated on putting a power setup in it someday.

Very nice. You might want to get your Saginaw pump all mounted up and see what the offset looks like. A good machinist can pop out an Aluminum power steering pulley about anyway you want it and likely pretty reasonable on price. I just took Lee a drawing at Auto Specialitiey's when they were in Stafford Tx. and he popped it out on the Lathe pronto.

PS: I Bet Keith Phelps here could do the same, give him a Ring.

I also noticed your alternator can be set back by a spacer change and then there is the Thunderbird water pump deal. I Think you can make your pulleys work with a little tweaking and maybe one new pulley if you try hard enough.
