General Discussion / Camshaft
« on: August 24, 2018, 04:11:37 PM »
I have a 69 Z28 with it's original 302. Before my ownership someone stuck a cam a bit different from the original Duntov 30/30 cam. Engine suffers from very low vacuum (5 in Hg) and in spite of advancing the cam 2 degrees and opening the valve lash the vacuum remains low. Good  idle is difficult to achieve and maintain and power brakes are also a bit of a problem.
   For you guys who run the Duntov 30/30 what kind of idle vacuum do you have and do you have your cam installed straight up or advanced? If advance how many degrees?

Restoration / teperature and fuel gauges
« on: May 11, 2017, 11:35:07 PM »
Restoring a 68 SS Camaro which has been stored since 1978.
Nearly finished and am having gauge problems. I installed all new AAW wiring harnesses and I cannot seem to get the fuel and temp gauges to work in the car thought they work okay when bench tested.
 My question is about the pink wire which provides power to these two gauges. I cannot light a test light on these pink wires at the gauges with the key on. The fuse is fine and there is power to the load side of the fuse.
Should not these pink wires be hot at the gauges? Thanks.

Restoration / Reproduction front header panel
« on: May 12, 2016, 09:52:36 PM »
Wondering if anyone has experience recently in repop header panels for a 68 camaro.
I have a repop, about 10 years old, to use on my 68 I am restoring. I have all original sheet metal ( hood and fenders included). The repop header panel is way off. It does not align with the hood and the accent ridge in the middle is much smaller than on the hood and on the original header panel which is damaged beyond repair.
Anyone purchased a repop panel the fits somewhat decently?? Thanks in advance.

Originality / 1968 Camaro SS Z21 option
« on: September 23, 2015, 02:22:41 AM »
Just bought a 68 Camaro SS coupe. It was originally a 350 HP 396, 4 speed car, LeMans Blue with white stripe and black vinyl top. It was built the 5th week of July of 68 making it one of the last 68 cars built.
I bought it from a friend who bought it in February of 1970. I have known the car since he bought it.
My question has to do with the Z21 option. The car has the bright work along the drip rail and the rocker panel moulding but no other evidence of Z21.
 Would it be uncommon for an SS car to not be ordered with the Z21 option? The front fenders are drilled for mouldings but they were not on the car when purchased in 1970. The rear wheel wells do not seem to be drilled for mouldings but are a bit mangled so is hard to tell. No bright work along the belt line or holes for same either.  Comments would be appreciated.

Restoration / 1968 Camaro Coupe rear subframe
« on: July 14, 2015, 11:06:02 PM »
   I recently acquired a 68 SS Camaro and it is a coupe. been stored since 1972. Car had been hit in the rear, not bad but will need to be on a frame machine to pull out a bit. Original paint and interior so worth working with.
   I have checked the Fisher body manual (Chapter 3) for both the 68 and 69 Camaros for factory dimensions of the underbody. I find a 3 to 4 inch difference between those two years on vertical dimensions f and g in the manual and these are essentially the kickup part of the rear frame.
   According to some of the vendors 68 and 69 take the same rear frame. Given the variance of the critical dimensions in the manual I don't see how the same part number would work for the 2years.
   Can someone lend some clarity to this matter? I would much appreciate.

Maintenance / Amp Gauge 69 Camaro
« on: June 28, 2012, 01:12:43 PM »
My amp gauge does not work. Needle stays at O at all times. Alternator is charging, battery is at 14.5 Volts with engine running.
I have checked continuity on the red wire running from the horn relay to the terminal behind the battery. It is fine. I have checked the continuity of the wires (black and black with white stripe) at the console plug in (at the 10 or so pin console connector).
I have continuity on both the console side of the connector and the firewall side of the connector. I have run a separate ground from the amp gauge to ground with no positive results.
My service manual does not help me trouble shoot at all.
I think I have continuity to the console plug in telling me the fusible links are intact. I am not so sure about my tests on the gauge itself. Any suggestions would be appreciated. I have read the many threads both on here as well as on Team Camaro but am now stumped!

Maintenance / Metering (or hold off valve)
« on: April 23, 2011, 03:43:11 PM »
  Have replaced the brake lines, master cylinder and booster on my 69 Z28. Bled the brakes and noticed a minor fluid leak from the rear of the round metering valve. Ordered a rebuild kit from HBC which consisted of three parts: the external rear button boot, the front o-ring and the rear cup rubber seal (which mine did not have in it when I disassembled it). Too bad the rebuild kit does not include the internal flat washer!
  Before I disassembled and now upon reassembly I noticed the bypass button on the rear of the metering valve cannot be pushed in, even when placed in the vice.
   I measured the length of the parts and then the length of the internal cavity in which they go when assembled and the distances are the same. What gives? No way for the rear button to push in! I have searched the several threads on this site and over at Team Camaro. No one seems to have run across this.
  I think there are a couple different designs of this metering valve but mine is like some others whose internals are shown on the various threads. How mine did not leak with out the rear cup seal before I replaced the other components of the system I do not know. Any thoughts from any one?

Decoding/Numbers / Power Steering Pump Pulley
« on: March 14, 2011, 03:25:12 PM »
I removed the power steering pump pulley from my 69 Z28. It is part number 3770509CE. Could some one tell me what the application(s) is/are for this pulley?

Restoration / Exhaust Hangers
« on: March 03, 2011, 01:33:20 PM »
What is the correct finish for the exhaust hangers on a 69 Z28? I am referring to the metal hanger brackets. I am assuming they were either unpainted or silver cadmium? Perhaps galvanized? Thank You.

Decoding/Numbers / 5468309 Master Cylinder
« on: February 25, 2011, 06:00:00 PM »
I just removed the master cylinder and booster from my 69 Z28 and installed the correct ones.
The master cylinder I removed is part # 5468309, broadcast code EA, and date code 10. What is the application for this?
The booster is stamped on the top ear 3239 (front) and CL on the rear. No other markings. What is the application for this?
Thanks in advance for any assistance.

Originality / DZ Distributor
« on: April 06, 2010, 02:25:28 AM »
How difficult is it to come up with a 532 CCW advance cam for the 1111480 distributor? What other GM distributors was this long slot advance cam used in?  Thanks.

Restoration / Oil line fitting
« on: March 23, 2010, 10:02:34 PM »
Needed to replace my mechanical oil pressure line and ran into the GM proprietary fittings.
Bought the nylon oil line with GM fittings from NPD as well as a new block fitting. No problem on the gauge end but the engine end is a different matter. My original GM fitting in the block is battered and will not seal. GM no longer has these block fittings. The block fitting from NPD is of the standard compression fitting type with a farrow.
What do folks do in this instance? I suppose one could simply cut the new nylon (plastic) line to remove the GM wedge shape swedge and brass insert and use the standard farrow type compression fitting. Or is there a source for the original GM block fittings? Thanks.

Restoration / Package Tray Moulding Color
« on: March 16, 2010, 04:16:01 PM »
 Have a 69 Daytona Yellow Z28 with the yellow houndstooth interior. I removed the rear package tray and need to repaint the metal moulding around the rear and sides of the package tray. Currently painted a satin black. Sanding shows yellow beneath the black. I assume this moulding was originally painted body color?

General Discussion / Dash Speaker
« on: March 14, 2010, 03:43:50 PM »
Can someone recommend a source(s) for an original type center dash 10 ohm speaker for my 69 Camaro. It has the AM/FM mono radio in it but the speaker is gone. It is the U69 option code.

General Discussion / Fan Clutch
« on: March 05, 2010, 04:18:55 PM »
Before I ask my question I did look up the available information on the CRG Reports on this subject and was educated somewhat.
I am looking for a fan clutch for my 69 Z28 which should be an Eaton with a CV stamping. I have located an Eaton clutch with a CH stamping presumably from an SS 69.
 Assuming the spacing from the water pump mounting surface to the fan mounting surface is the same or very close between the CV and CH clutches does anyone know the internal differences between these two clutches? Any idea if these differences would render the CH clutch non-usable for the Z28 application? Thanks.
