Maintenance / Re: Help in diagnosis

  Easy enough. Once it warms up take the air cleaner lid off and see if the choke is open. Or start it up cold and see if the choke opens as it warms up. It could be the accelerator pump. This damned ethanol gas eats up rubber like Ms PacMan. Once things get warm and expand, the pump diaphragm could be letting gas slide by it, causing the stumble. On the electrical side, I've seen coils break down when warmed up and the symptoms are similiar. Hard to pin down, but when in doubt revert to the basics. It's likely something very simple. Good luck and hope this helps.

  That thing is so sweet that sugar is jealous. Outstanding and a serious high-5!

  Ground Up lists the return spring as black for a Quadrajet, green for a Holley. Hope this helps.

Thanks, fellows!

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.

  Mike............that 1/8 turn roughly equals 1/16". And yes....once you fire it up they don't need adjusting again. It sets the lifter plunger just right to eliminate pump-up when you spin the engine up.

  For anyone reading who has a hydraulic cam, I have a foolproof method of adjusting juice lifters. Use the sequence as suggested above by cook. To adjust the valves, back off of the rocker arm until you can spin the pushrod between your fingertips. Then slowly tighten the nut down until the pushrod stops rotating. Turn the nut EXACTLY one-eighth of a turn and your hydraulic lifter is set. Do not go 1/4-turn. I've found that with a performance or even stock cam, this sets the lifter preload perfectly. Hope this helps someone.

  Soda blasting is good for items that are fragile or easily eroded. Hope this helps.

  I need two. If you get up and running, count me in.

  Worst comes to worse, the cam could be going flat. Just a thought. Good luck!

Maintenance / Re: intake

  I always put sealer around the water passages, and a thin dab at the bottom of the intake ports just to make sure they won't suck any oil from the lifter valley. I've been using just silicone on the rails for years. It doesn't push out and once set, doesn't blow out or leak. I like Permatex Ultra Black. My 2 cents and good luck!

  They found mine. It was delivered to Indian River Chevrolet in Cocoa, Florida. It says the delivery code was 283 in Zone 26. It lists the production date as August 29, 1968.
  This raises a question: My car is #1750. Shouldn't it have been built in August 1967? Perhaps I'm confusing something here, but weren't the cars built to coincide with the model year release in the fall of the old model year?  I.E. weren't 1968 model cars released late-year 1967? Maybe I'm all wet here. Help!

 I had Chevy Muscle Docs run my VIN and was excited to possibly learn more on the history of my '68. Unfortunately I was one of the few whose VIN could not be deciphered and identified. My car is a very early Norwood perhaps that is why it couldn't be traced. But kudos to everyone else--you guys must be thrilled to have gotten your info. Keep 'em rolling!

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!

Maintenance / Re: Speedo / Gauge cluster - bad connection ?!?!
« on: May 27, 2014, 04:00:11 AM »
 Run a ground wire from the back of the cluster to the dash. This exact same thing happened to me and that was the problem--a bad ground. The high beam indicator works because the center dash screw grounds it. When you dropped the thing down something on the cluster probably hit a ground on the metal dash. Not saying 100% this is your problem, but it was mine. Good luck!
