[QUOTE=yostusota]Anyhow what's the opinion on using the new shafts cam?? I have found that it used to be removed off the old one and brazed onto the new one..is this really necessary? ?[/QUOTE]

I've never seen one like that myself. Sounds kinda goofy...why the heck would someone do that, anyway? I could see doing it if you had a tach drive shaft, and needed a new cam, so you would steal one off a non-tach drive shaft, but...sounds a lot like something we would do back in the day, when we would have a ton of parts laying around gather dust, and no $$$$ to buy anything we needed. Can't see having to do that with the reproduction, and aftermarket suppliers out there these days.

You'll have to cut the old bushings out, if you do need to replace them. A really sharp chisel will do if yer careful. Check with yer Snappy or Matco guys...they have special bushing cutters...basically weird looking chisels.

The shaft from the '74 danascar has would work, too...

From what I found is GM used 38 different advance cams between 68-74 so I guess the thought is that changing them will keep the stock advance curve..idk..I think if it looks ok I will use the new one and be done ..I can always modify the advance hole stop if need be..I do have a question about a stop button that can be installed into the stock housing..pn X2557 in the CA catalog..you have to machine the housing and install this brass bushing into it repairing the housing..one of those parts that I had to have..don't think my housing is all that bad but it would make a permanent repair..anyone done this??oh and I have to say ordering parts around 10 am and having them on my front door by 9 am is a wonderful thing! Really am starting to be a CA parts fan.

How can you order parts at 10, and have then an hour before(9) you ordered them By golly, THAT'S some DANG good service! What...they readin yer mind er sumptin?

I've never heard of the cams on the dist shafts being different...unless we're talking about two different things. I'm thinkin you are talking about the cam that the points rub on...right? If so, then afaik, they're all the same.
There are different advance vacuum cans, of course, and different weights, springs, and slots on the mechanical advance dohicky....all of that is removable/changeable.

Well I just got lucky with the order then..they are only 80 miles from my house..so if they ship the day I call I get it the next morning..the part I am talking about is welded to the top of the shaft itself..advance cam..not really a big deal..I am now trying to put in the brass plug for the gears to ride on..fun fun..will post pics once I figure it out..

I think what Joel meant was that you probably ordered the part at 10 PM, not AM. As he said, you can't get parts BEFORE you order them! Anyway, hope it turns out OK.

You guys are being silly..ordered parts 10am on Monday have them by 9 am Tuesday.

Now THAT makes sense!!!!

Here's a fun update on the tach drive..finally got the new brass bushing in..perfect..should get the new vacuum advance tomorrow! ! Then its setup time.

Rich

You've only got a couple of weeks, Rich! Looking good!
