1  Camaro Research Group Discussion / Maintenance / Re: No power to the solenoid? on: Today at 09:44:39 PM
I'm in the middle of troubleshooting the same problem. Mine would fail occasionally and mostly gave me trouble when the engine was hot and recently it stopped working altogether. I think that I traced my problem to a combination of old dirty connections with the worst of them being in the console wiring harness to the neutral safety switch.

The problem is that not enough power is getting to the starter solenoid to activate it. This can be caused by a weak battery or one or more bad connections between the battery and the starter solenoid switch.  It can also be a bad connection between the body of the solenoid switch and the negative battery post.

After studying the wiring diagram I learned that the starter solenoid circuit is as follows:

1 fusible link from battery + to terminal post on the radiator support near the battery.
2 wire from terminal post to horn relay
3 wire from horn relay to the bulkhead connector on the firewall behind the power brake booster
4 wire from the bulkhead connector to the ignition switch
5 wire from ignition switch to the neutral safety switch in the floor console (auto transmission)
6 wire from the nuetral safety switch back to the bulkhead connector
7 wire from the bulkhead connector to the starter solenoid

Any and all of these connections can get dirty and cause resistance in the circuit that adds up to a problem.  Or as stated previously it could be as simple as a weak battery or bad battery cable connection.

Happy hunting and I'd love to hear what you find, ,Mike.
2  Camaro Research Group Discussion / Maintenance / TH350 tranny kickdown cable seal on: Today at 05:29:51 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.

I received the cable and it's the same as the old one that it is replacing. There was a time when I had a Nova 350cid engine in the car and it is possible that my old cable was a Nova cable from that engine. Joparts delivered fast and the part was just as he described it so I have to say that all is well.

I still haven't received a reply to my email but the cable shipped the day following the auction end.

In a separate thread I asked for advice on an accelerator cable for my 68 Camaro with 327 engine. The 68 originally had a steel lever mechanism on the V8 engine and a cable on the L6 engine.  My car was originally an L6 and so it has a cable which is a little long for the V8. In searching around the net I found that a 1970 - 1972 V8 Nova cable will fit well and that is what I ordered from joparts. 'll post back here when it arrives on how it fits my car.

Well I'm about to find out, I just bought an NOS OEM accelerator cable from him. He has a lot of nice parts on ebay and an excellent feedback but I sent him an email this morning and he hasn't replied. Normally that would put me off but it is the only OEM cable that I have been able to find.

Has anyone dealt with the ebay seller joparts? Good Bad or Ugly?

Nova cable attaches to the firewall with one screw. I can take a pic. of the Nova set-up if you need it. The Nova Q-Jet cable will work. The Nova Holley cable has a different end.

Thanks for the confirmation and no need to post a pic. I have it from a few different sources now that it will work so I'm going to order the Nova cable.

Have you checked what Lokar has ? Quality products.

No I'd prefer the stock look. While the engine is not the original L6 it does look stock under the hood. There are a couple of problems that a Camaro guy would pick up on like the 1967 valve covers and oil filler in a 68 car but most people don't notice that.  I have the stock air filter and exhaust manifolds and for the most part it looks like a stock camaro.

So far I have come up with GM part 3998632 as fitting early Nova with four barrel carburetor. Can anyone tell me if the Nova cable attaches to the firewall the same as the L6 Camaro cable? Mine is screwed to the firewall.

Thanks for all of the replies and suggestions but I'm looking for someone who has already been through the conversion and knows of a cable that will fit. I'm trying to avoid buying two or three cables to find the one that works. There are differences in length and how they attach to the carburetor, firewall, manifold and gas pedal. Nothing is simple.

Mike.

It was a hard lever action linkage in 68 on the 327.

68L30

Do you know if the cable assembly is interchangeable with the lever assembly without altering the firewall?

Mike.
12  Camaro Research Group Discussion / Restoration / Re: First Gen accelerator cable question on: March 29, 2015, 10:17:36 AM
Thanks but I the engine is not original and I prefer the cable to the lever. I also think that the hole in the firewall is different between the two versions so it wouldn't be easy to convert.

Mike.
13  Camaro Research Group Discussion / Restoration / First Gen accelerator cable question on: March 29, 2015, 09:58:01 AM
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.

Bryon:

I bought my 68 Camaro in 1987 with a matching number l-250. The pump has the number 16 cast in it and is stamped 30454 with the letter "A" just below the numbers. I believe that the pump is original but can't be sure.
