Originality / Help with steering ratios
« on: June 25, 2016, 11:01:09 PM »
I am trying to identify replacement steering parts for my 68 standard convertible and can use some help.

When I got the car it had two different length steering arms and I replaced the shorter of the two with a longer one to make a matching set. I do not know the significance of the two different steering arms....maybe different years....different ratios?? The steering arms now match and the steering wheel is now just about exactly three turns from stop to stop.

While shopping for steering linkage parts I have learned that the pitman arm is available in three lengths, 5 3/8 for the standard steering gearbox, 5 7/8 for the quick ratio steering gearbox and a 5 3/4 which I can't identify yet. My pitman arm is 5 7/8 center to center.

Now to my question - has anyone made sense of this mix of parts? I would appreciate anything that anyone can tell me about the different steering arms, pitman arms and steering boxes. Is my three turn steering quick ratio? Standard ratio? Mid ratio?

Thanks for any help, Mike.

Maintenance / 14" tires are hard to find these days
« on: June 01, 2016, 01:46:57 PM »
I've been searching for a set of raised white letter tires for my 14x6 rally wheels and I'm not having much luck. It looks like all roads lead to BF Goodrich T/A radials. I found that Cooper makes a tire in this size and that's about it.

So does anyone here know of any other 14" rwl tires that I can look at?

TIA, Mike.

Restoration / 1968 standard horns
« on: May 11, 2016, 02:21:46 PM »
Has anyone tried the aftermarket horns? Do they sound correct and loud? I tried to rebuild my original horns with a rebuild kit but they came out making a low volume sound that reminds me of a cow.

Any recommendations?

TIA, Mike.

Maintenance / Starting problems
« on: June 05, 2015, 08:13:48 PM »
I've been troubleshooting a starting problem for a month now and several times I have thought that I've found the problem because I make a correction and the car starts fine. Then a few hours or a few days later it goes dead again. I've corrected a bunch of flaky connections and replaced the horn relay, ignition switch and neutral safety switch.

My question - what should the voltage be at the starter solenoid with the key in the start position? I am getting a large load when I turn the key and the voltage at the solenoid purple wire is about 8vdc. The solenoid is new.

TIA, Mike.

Maintenance / Fusible link wire gauge
« on: April 29, 2015, 11:52:05 AM »
Can anyone tell me the correct gauge fusible link to use on the 10awg red lead to the voltage regulator on my 1968? The wiring diagram that I have seems to say that the 10 gauge red wire is reduced to 20 gauge wire at the regulator. Some wiring diagrams do not have a fusible link at the regulator at all. Is the output of the alternator a factor in determining the correct size? The original looks like about a 18awg or thereabouts.

TIA, Mike.

Maintenance / TH350 tranny kickdown cable seal
« on: April 27, 2015, 10:29:51 PM »
I converted my 68 Camaro to a 3 speed TH350 transmission and am having trouble finding a seal for where the detent/kickdown cable enters the transmission body.  I have read that there is a tophat shaped seal that will work but I can't find it online and the seal that NAPA came up with was too large.  The seal that I need will have a 5/16" inside diameter to fit the cable housing.

TIA, Mike.

Restoration / First Gen accelerator cable question
« on: March 29, 2015, 02:58:01 PM »
Years a go I converted my 1968 L6 Camaro to a 327 engine with quadrajet carburetor. At that time I was able to use the 6 cylinder accelerator cable on the new engine but it was a little bit longer than I would like it to be. Also I recently read some where that there is a Nova cable that was used with a 350cid engine that fits a little better than the L6 cable.

So my question -  has anyone been through this that can save me some leg work and trial and error finding a good fitting cable? Did the 68 Camaro use a cable with the V8 engine?

TIA Mike.

General Discussion / Found a cool site

Some of you may already know of this but it's new to me. It a site called The GM Heritage Center. It's interesting reading and has downloadable information packages that are loaded with technical detalis.

General Discussion / tires for 14 x 6 rally wheels
« on: June 26, 2013, 09:10:21 PM »
My 68 is due for a new set of tires and I'm looking for a tire that looks nice and beefy on the car to give it a little bit of a muscle car look. I'd love some size recommendations and really love any photos of your cars to see what the tires look like on the car. I'm considering maybe a different profile on the rear than the front and maybe even 14" on the front and 15" on the rear.

Thanks in advance, Mike.

Mild Modifications / powerglide to th350 conversion
« on: June 09, 2013, 12:34:46 PM »
I recently converted my 68 convertible from the powerglide transmission to a th350 and would like some input from anyone who has done the same. The conversion was almost a straight up bolt in swap with a couple of exceptions. I found everything that I needed to hook up the horseshoe shifter and kick-down cable at Shiftworks and I thought that I was all set until yesterday when I went underneath to look for a tranny leak and noticed that the rear motor mount cross-member covers the two rear drain pan bolts on the tranny and it looks just about impossible to get a wrench on them.  It looks like I may even have to unbolt the rear mount and lift the engine to get the pan off.

Has anyone ever seen this and how did you deal with it? Any input would be be appreciated.

Mike.

Maintenance / Quadrajet accelerator pump problem
« on: May 08, 2013, 08:55:24 PM »
I have a poser for the group. I've rebuilt more Q-jets than I can remember and have never seen anything like this. The carb is completely rebuilt including new throttle valve bushings and runs great. There is no hesitation and it accelerates smoothly and it idles great but something very odd is going on.

When I turn the engine off the accelerator pump is not working at all making it very hard to start cold! I turn the engine off and quickly pump the throttle while looking down the carb throat and it is not pumping at all. I start the engine and looking down the throat I can see that the pump is working fine. Shut it off again and no pump. I can see the pump moving up and down so the only thing that I can figure is that the float bowl is going empty as soon as I turn the engine off but if that is the case then where is the gas going? The engine does not flood and restarts easily when warm and when I loosened the fuel line at the carb there was still pressure in the line.

I'm about to take the top off the carb but thought that someone here might have an idea before I do that. Any takers?

Mike.

General Discussion / powerglide to TH350 conversion question
« on: February 08, 2013, 12:36:40 PM »


I recently replaced my powerglide transmission with a TH350 and have a question concerning the horse shoe/staple floor shifter. The shifter is adjusted and works with one exception, when I pull the shifter into low the tranny  lever reaches the end of it's travel and the car shifts into low before the shifter reaches the low gear detent. In other words, the shifter travel is too long for the transmission lever travel.

So my question is how to correct this and make the transmission lever travel match the travel in the shifter. Is there a longer lever/arm that I can put on the transmission shift shaft? Do I need to change the shifter detent?

I have searched the forums here and can't find a solution to my problem. I have read that GM used the stock horse shoe shifter with both transmissions and that it should work with both the PG and the TH350 without altering it.

I'm sure that this conversion has been done many times and would appreciate any help that you guys can offer.

Mike.

Restoration / 67 327 oil filter bypass valve
« on: January 06, 2013, 02:32:21 PM »
I searched the forums and around the net and can't find what I'm looking for anywhere and CRG has been my favorite source of info for years now so I'm turning to you guys first.

Is anyone familiar with the oil filter bypass valve plate that GM used in the early small block chevy canister type oil filters?  I have the original valve plate and am considering replacing it for new in my new engine but sometimes a new aftermarket part isn't as good as the original.

So my question is:  Does the bypass valve ever need replacing? Does it have any moving parts inside that can stick of does it just divert some oil around the filter? Has anyone ever taken one apart to see what's inside?

TIA, Mike.
