Decoding/Numbers / original DZ carburetor?
« on: August 17, 2014, 06:34:49 AM »
  Hi fellows. I may have stumbled upon something and hope someone can help. I have what appears to be an original GM DZ carburetor. Stamped on the choke horn are these Holley numbers from top to bottom: 3923289-DZ  LIST 4053   902.
  It has the appropriate choke pull-off.
  The PCV hose tube is on the right-hand side of the baseplate.


Maintenance / funny fuel gauge
« on: July 31, 2014, 04:58:47 AM »
  Hey guys. I replaced my old gas gauge with a brand new one and have a problem. The car has half a tank of gas in it, but the gauge reads 3 notches below empty! It isn't even in the gauge register zone. The sender is a brand-new AC  NOS  piece and I know it's good. I know that sometimes if these gas gauges are dropped that the needle can be jostled out of position because only a tiny pin on the back of the needle holds the needle on. Would it be feasible to take the gauge back out, move the neeedle to half a tank, and expect it to read correctly from there? Or would power from the sender have to be going to the gauge when the needle is repositioned? Or is this even possible? I hate to think I just dropped $200 on a new gas gauge that isn't worth a hoot. Thanks!

Restoration / Cowl Induction hood
« on: June 15, 2014, 08:05:20 AM »
  Hey guys. I have a question about the ZL-2 hood and how it was trimmed out from the factory. Was the overhang at the flapper valve and cowl blacked-out or was the underside the color of the car? Also, was the entire underside of the hood over the engine blacked-out or was it the color of the car? If it was blacked-out, was it gloss or semi-gloss? I've never seen this question addressed and am curious. Thanks.

Decoding/Numbers / Big Block engine ID
« on: May 30, 2014, 02:30:10 AM »
  Hi guys. I have a friend with a big-block engine and I can't figure out what it is. The number on the block pad at the front is CEF 178770. I can't find CEF in any reference codes. I seem to recall that CEF designated a GM replacement engine or a crate engine. Has anyone else run into this, or does anyone know what this engine could be? Any help woud be greatly appreciated. Thanks!

General Discussion / 1968 speed warning indicator
« on: April 25, 2014, 06:00:48 AM »
  Hi folks. Can anyone explain how the electrical part of the speed warning indicator works on a 1968 Camaro? I've gotten an aftermarket speedometer with the needle and cable, and the wiring harness. But I can't find a buzzer except on Ebay, and all of those have 3 terminals on them. The speedometer itself has black and brown wires, the harness has a pink and a white wire. Is the black speedometer wire a ground? It looks to me as if the black wire grounds to the cluster and the harness wires are both hot. Is the needle the switch that connects the 2 hot wires so that the buzzer goes off? That would explain the 3rd terminal on the buzzer, where the wire from the speedometer would plug in. If not, what makes it trigger when the speedometer indicator needle eclipses the speed warning needle? Also, when the speedometer needle gets to the preset speed, is it supposed to stop where the warning needle is set? Anything to help me understand this system would be greatly appreciated. Thanks!

Restoration / Automatic brake pedal
« on: April 17, 2014, 05:31:18 AM »
  Hey guys. I got the automatic pedal swapped in the '68 and now there is a problem: the pedal sits too high. It's an aftermarket piece from Rick's--surprise that an aftermarket part doesn't fit quite right. Everything swapped fine....the bushings and pins and master cylinder rod etc.. The new pedal is against the rubber bumper just as the stick pedal was, but it's about 3-4" too high from the floor and it's uncomfortable to cock my leg up and push it. Just another heads-up about aftermarket parts. If you can find an original part....FIND IT! It's worth the search and money.

« on: April 15, 2014, 05:19:12 AM »
  Hi guys. Can anyone post a wiring diagram of how the cowl harness hooks up at the fuse box and what color wire goes to what? I have an aftermarket (of course) harness and it has 2 wires with 4 plugs coming off them--2 plugs per wire. The wires are pink and tan. Thanks.

General Discussion / Brake pedal swap
« on: April 02, 2014, 07:31:23 AM »
  Hey guys. I need to swap a manual transmission brake pedal/clutch pedal setup for a single automatic brake pedal on a '68. I have the automatic pedal and pivot pin to make the change. I also have the cover for the firewall where the clutch pedal rod goes through. Will the automatic pedal simply replace the other pedals with no other parts? It looks as if the other assembly will just drop out when I take everything loose and remove the pivot pin, and the automatic pedal will fit right back in. But before I take the dash apart I don't want any surprises. The car has manual drum brakes if that makes any difference. Any advice would be greatly appreciated. Thanks!

Maintenance / speed warning buzzer
« on: December 27, 2013, 06:42:23 AM »
  I bought a new speedometer for my '68 and it has the speed warning needle. I'd like to make it functional, but no one offers the buzzer that goes on the back of the instrument cluster. Does anyone know of a late-model buzzer or chime that I can adapt to it? Since it won't be original, I don't really care what it fits. I'd just like the thing to buzz when it exceeds the set speed. Thanks.

General Discussion / '68 on the main page

  Wow.................sweet ride. The Vigilites and remote door mirror and Goodyear tires and gray mags and old USA-1 tag set that baby off. Well done! I hope my '68 turns out as well.

General Discussion / Speed Warning Indicator speedometer
« on: November 30, 2013, 09:22:08 AM »
  My '68's speedometer crapped out. It won't indicate mph anymore but the odometer still works. I see that Rick's has a replacement with the speed warning indicator option. I'll have to buy the adjustment cable as well, and I'm wondering where I might find or adapt a buzzer since no repros are available? For a few more bucks I can increase the potential value of my car if I can make the thing functional.
  I had a '67 RS with this option but it never worked. How much extra $$ and hassle can I expect to retrofit this option to my '68? I know the cost of the speedometer itself and adjustment cable--my question is how much more involved does it get? Are these repro speedometers worth a crap? Any feedback would be much appreciated. Thanks!

General Discussion / cowl tags
« on: November 24, 2013, 06:59:18 AM »
 Is there any way to get a cowl tag for one that is missing? I have a friend with a 1968 SS 350 car that is missing the cowl tag. Does anyone reproduce them or is there a market where can one be obtained from a junked car? Any help or feedback would be much appreciated. Thanks.

Restoration / Cowl hood flapper valve
« on: October 17, 2013, 02:49:02 AM »
Hey guys. Just curious-did the flapper valve frame on the cowl induction hood come black or painted the colorof the hood? I'm retro-fitting an operational cowl induction system to my '68 and the question came to mind. Also--where on the firewall does the cowl induction wiring to the fuse box pass through? Thanks.

General Discussion / wiper motor wiring
« on: October 03, 2013, 05:20:35 AM »
Hey guys. Does anyone have a schematic that shows how the wiper motor is wired on a '68? My motor has 4 terminals on the speed side and 2 on the washer pump. I have blue, light blue, yellow and black wires. My wiring diagram is vague on what wire goes to which terminal and there seems to be a double jumper wire between two of the terminals. My original plastic loom clips are no good and I just have wires with brass connector clips on the ends. I've installed a rebuilt motor. I have power to the wires at the motor but the motor won't run. Any help would be greatly appreciated. Thanks.

General Discussion / Noisy distributor
« on: July 04, 2013, 05:47:26 AM »
   Has anyone ever heard of an oil pump driveshaft being too short? The tabs are only engaging the distributor shaft by about 3/16". The distributor is a new Pertronix that has run perfectly in another engine and matches the length of a stock distributor exactly. I've shimmed the gear and taken out any excess slack so it couldn't climb up under resistance from the oil pump. The oil pump shaft is a new ARP that matches a stock shaft in length. The engine is a 383 stroker with a Comp Cams small base-circle roller. The manifold is a Team G that--as with the distributor--worked perfectly on another engine. The heads are AFR 210s from the same engine. Nothing is different except for the short block. The valves are lashed correctly.
    When running the engine has a loud clacking sound that sounds like a loose rocker arm, and I believe it's coming from the oil pump driveshaft jumping around because it isn't fully seated in the distributor shaft. Oil pressure is fine. I've never encountered this before and would appreciate any advice or feedback. Thanks.
