31  Camaro Research Group Discussion / Originality / Re: Master cylinder cover on: September 24, 2014, 08:21:14 PM

I don't have many important pieces still left on my car that I could reasonably believe were original BUT I do believe that this master cylinder/cover/booster is original.  This is a valid datapoint for this '69 Z built first week of October '68.  So glad I have something to contribute.  Grin

This is the line that made me grin:

"It will require trailering home OR WE CAN MAKE IT SMALLER for shipping if desired"  :~D

With what?  a blow torch?!?!?!  -HA!

on second thought......From a business standpoint, Bob should really be giving that car away to the first trailer that shows up.  He can then sell back all the pieces he took off of it to the new owner.

Maybe it was originally from a Chevelle or Vette with the HD clutch?

34  Camaro Research Group Discussion / Maintenance / Re: Timing out of wack on: August 25, 2014, 05:24:04 PM
The keyway is located something like 9 degrees off the TDC mark on the balancer.  Balancer timing mark will line up with timing tab at #1 TDC AND at #6 TDC.

The crank can't be wrong.  if you are actually at #1 TDC FIRING position, the timimg mark will match up with the timing tab (at maybe 2:00).  Anything else (IE 7:00) is not possible. If the keyway is near 7:00..... the #1 piston is at the BOTTOM of the cylinder.

Distributor can't be installed right. You can't move the keyway that is cut on the crank, right?

Go back to post 2 - Pull the distributor out and put your finger over the spark plug hole while someone else bumps the engine.  When the air puffs out you line up the timing marks on the balancer and the timing tab then drop the distributor down in place with the rotor tip ending up roughly pointing at the battery. See the chilton manual for the cap wiring firing order and correct distributo tower to start the firing order.  Be sure to get that distributor all the way down where the oil pump shaft lines up and the distributor is all the way down on to the intake manifold. 

This has got to be the issue.

It will not run 180 out.  The shear key might be missing but I suspect this is not the problem.

How did you verify the balancer?  How are you checking the timing?  Where does the rotor point when the engine is on #1 TDC Firing position?

Which tower are you using for #1 cylinder?  Firing order is probably fine if it ran well.

36  Camaro Research Group Discussion / Maintenance / Re: Timing out of wack on: August 25, 2014, 11:05:25 AM
My guess - Re-clock the distributor to where it should be and verify the wire positions on the cap.  Put your finger in the #1 spark plug hole and crank the engine to verify #1 TDC firing position - it will blow your finger out. This situation is probably not as messed up as you think it is. Some times people drop a distributor in after a cam swap in what they believe is the right #1 TDC Firing position but it is actually at #6 TDC.  Happens ALL the time.

37  Camaro Research Group Discussion / Restoration / Re: Motor mounts on: August 25, 2014, 10:58:23 AM
The locking mounts are fine but keep in mind that the different engines used different mounts and stands.  In case you didn't know - All small blocks do not use the same mounts.  I know that sounds crazy because it really is. Smiley


38  Camaro Research Group Discussion / General Discussion / Re: Harmonic Balancer for 302, need the circumference? on: August 19, 2014, 09:39:00 AM
Wrap a measuring tape around the balancer.  Divide by 4.  Much more accurate and practical.  String is great too.

Make marks for every 90 and another mark for 36 advanced for setting the timing while you are at it.

BTW - "360 = Circumference" so measure around the damper then divide measurement by 10 to get the measurement for 36 point from the TDC mark. Smiley

39  Camaro Research Group Discussion / Maintenance / Re: where can I buy a manuel steering gear box rebuild kit on: August 18, 2014, 11:28:40 AM
Anybody have suggestions on rebuilder for a Saginaw power steer gearbox


Tom Lee did mine and it came out real nice. The overhaul kit is not enough parts by itself to finish the job in my experience.  You usually end up needing other parts and those have to be tracked down.  Then there is the lash setting procedure to do as well....  I decided to send it to Tom.  He advised me to make it higher effort than it was originally and I really wish I had taken him up on the offer.  The factory boost is too much.  Can't really change it easily after the fact.  Same ratio but better road feel.  I am picky about originallity but this is one place it makes sense to go away from the factory spec in my opinion.  His too. Smiley

He did stamp his number on the top cover so you might want to talk to him about that if you are particular.

Coil Spring with the original "YF" tag barely hanging on.   Both Springs tags were unreadable from the years of weathering.   The Brake backing plates lost their stickers as well with both leaving prints of where they once were.  Sad   The Brake Distribution switch and it's bracket.

You might try carefully soaking that spring tag in water.  I found an original tag on mine that was impossible to read unless it is wet.  Then you can see the codes.  Just something to try.

41  Camaro Research Group Discussion / Maintenance / Re: Running Hot? on: July 30, 2014, 11:28:54 AM
Yep - the only thing else to do is slide a stainless steel shim in between the intake and the head on the drivers side right in the middle of the manifold to block that passage.  It will help to reduce the cooking of the carburetor and fuel percolation. Only do this if you have eliminated the heat riser function.

Just go to the kitchen when your wife is not around and find a flat bottomed stanless bowl.  Cut out a flat piece of material with tin snips just wide enough to fit between the manifold bolts in the center of the drivers side. Bend a small tab over to help you push it in.  Loosten the manifold bolts just a little and see if you can slide that metal down in there between the gasket and the intake. Try not to disturb the gasket too much.  Tighten the bolts back up and see if that helps.  It worked for me when I had the percolation issue.

PS - if you go snatch the bowl when the wife is watching, you are a BOSS!  Cheesy

Good luck!

The intake manifold ehaust heat passage will still flow some exhaust even if the flapper is removed.  You can block the non-choke stove side of the intake at the passage and the choke will still work from the heat migration in the aluminum but it might be a little slower to pull off.  Not a big deal.  If the passage is blocked on one side, no exhaust gas will travel through inside the intake manifold.

43  Camaro Research Group Discussion / Maintenance / Re: Running Hot? on: July 21, 2014, 09:18:45 AM
Timimg retarded? 

I would use a stainless steel shim to block the heat passage in the intake manifold/head on the drivers side only.

Do you have an Infra red heat gun to verify the actual temperature?  Nice to have or borrow.

44  Camaro Research Group Discussion / Originality / Re: Did all cowl induction air cleaners have the vent tube?? on: July 14, 2014, 03:41:46 PM
'69 would obviously need the crankcase vent inlet tube.  How else would PCV air get in the crank case?

Makes me think about the '67 crankcase ventillation system.......Not sure about that one.  Maybe somone more familiar with the '67 setup will add soemthing here?   HMMMM???

45  Camaro Research Group Discussion / Decoding/Numbers / Re: Rear seat bulkhead #8 and #1 yellow chalk marks on 69 camaro on: July 14, 2014, 03:39:20 PM
Just a thought - Might not be an "8"...... It might be a "B" for blue interior?
