1336  Model Specific Discussions / Trans-Am Camaros / Re: 2013 Monterey motorsports reunion: Who's going? on: August 19, 2013, 03:43:01 PM
The yellow '69 Z28 in the first photo below once belonged, or still belongs, to Rick Sterbins?  (I see Sterbins automotive on the fender...)...  Attached is a photo from the Supercars.net, showing the same car in the 2010 Monterey Reunion.   

http://www.supercars.net/gallery/119513/2484/952175.jpg

I'm almost positive Richard is the same 'Rick Sterbins' I knew from the USAF at Keesler AFB, around the '69-70 time frame.    Rick had raced a '66 Mustang notchback (one of a small handful of Shelby-ized race notchbacks) in Europe and all over, but returned from Europe, sold the Mustang to a friend of mine (Mike Seus) who converted it to the street.  Rick then bought a yellow '69 Z28... Smiley    I'm guessing this is the same Z28 he bought back then?
1337  Camaro Research Group Discussion / Originality / Re: Correct starter for '67 - 327 on: August 19, 2013, 03:32:48 PM
Does anyone KNOW WHY  different PN's were used?   

First gen Z28s, which were the highest compression small block engines, all had manual transmissions.  The 'books' say that PN 1108367 is correct for the Z28, and for all manual trans small blocks.   Do automatic trans cars requires a different starter?   Is this typical that auto cars and manual cars get different starters?   Is the difference the torque required, OR the teeth on the starter drive gear?  or ??     What's the difference and the reason for it? 
1338  Camaro Research Group Discussion / Originality / which Headlamp retainer is correct for 69 RS ? on: August 19, 2013, 03:25:05 PM
When I disassembled my front clip and all the RS parts, I noticed the car had two different size (depth) Headlamp retainer rings.   These appear to be identical except for the depth, and both/either work fine.    One is approx. 13/16" deep, and the other is 1" deep.   Which of these are correct?   or did GM use both sizes interchangeably?   One corner of my car was hit before I bought it in the mid 70's, so I'm not sure if both these parts are original from the factory, OR not.  Your help greatly appreciated so I know which of these to replace.. Smiley   Photos are attached...

Ed, others,

Thanks for the information on the Z28 exhaust (head) pipe diameter... and that 9May letter would seem to put the question on NC8 to rest (on Camaros), as it stated the *effective date* for discontinuation of the option is May19.   To me, that says unless your car was produced on 18May or earlier, it has zero chance of having come from the factory with NC8...
1340  Camaro Research Group Discussion / Originality / Re: Exhaust (Another Exhaust question) on: August 15, 2013, 03:53:41 PM
For late '69 Camaros, after discontinuation of the NC8 (chambered), and after the introduction of the resonators to the standard transverse muffler system, What was the diameter of the exhaust (head) pipe off of the manifolds??    People who sale these, list both 2" and 2-1/4" diameter.  Which is correct, and acceptable in the judged original classes?
1341  Camaro Research Group Discussion / General Discussion / Re: I found a Sequoia Green Z28 with air plenum 9 k miles ! on: August 13, 2013, 02:27:44 PM
My 69 RS Z came with no guages. My 69 L78 had none either not even a tach.
I assume your 69 L78 was an early car, did they eventually make the tach mandatory on the L78 cars, like they did on the Z?

Just for sakes of accurate terminology, the tach was not *mandatory* on the Z28, but it did become *standard* equipment later in the '69 year.  The only *Mandatory* options for the Z28 were the disk brakes and the 4 speed manual transmission! .. Smiley

Continuing with the discussion about factory gauges in race cars:
While I did not race my Camaro on a track, I did (as most Z-owners did) participate in some competition on the street.. Smiley
Attached below is how I addressed the 'sloppy tach' issue in my 69 Z28 in the 70's when I was driving it regularly.  I removed the original tach and the plastic housing around it (and saved it for installation later - which is now.. Smiley...  then I bought an extra plastic cover and cut out the 'clear face portion', because it interfered with the larger Sun Supertach.  I then installed the Sun Supertach in the same location as the factory tach came from the factory, and installed the modified plastic cover.   Photo attached.   This approach worked for me, because in the late 70's, I didn't want to make any 'non-recoverable' modification to my very original Z28.
Note:  I did 'trust' the mechanical oil pressure gauge which came in the console gauge cluster, so I did no other mods to my car (other than a Mallory Rev Pol and Judson electronic magneto, and some internal engine parts.. Forgedtrue pistons, lunati blueprinted cam, etc  and it would rev well beyond the 6500 rpm that I *tried* to observe.. most of the time...  Smiley

I'd like to see the height on one which sat unsprung for the last 40 years vs sitting with the suspension compressed.
measure your rocker height and compare to Chevrolet's spec (from the AIM), and let us know...?
1344  Camaro Research Group Discussion / Restoration / Re: Correct 69 Z/28 Coil Springs on: August 10, 2013, 11:22:58 PM
take a photo on the same plane as the top of the front tire, or do some measurements from the top of the tire to the top lip of the fender.  Yours looks closer to 'factory' Z28 than James, but the perspective of your photo makes that hard to see.

Copo, I've plugged in your data for you.   You didn't say if it was an RS, but I assume NOT?  and no stamped PN?

It would be very interesting, if you measured the distance from the bottom of the rocker, both sides, at front of rocker and back of rocker.   That would give us a good comparison to 'spec'... ?  make sure you're on a good level surface to get the best measures with the tires properly inflated.
1348  Camaro Research Group Discussion / Restoration / Re: Correct 69 Z/28 Coil Springs on: August 09, 2013, 10:31:18 PM
to me, it looks between and inch and 2 inches high in front.   I expect to see the top of the fender be approx. even with the top of the tire in front sitting on level ground (for Z28s)..
1349  Camaro Research Group Discussion / General Discussion / Re: Chambered Exhaust Option - 69 Z on: August 09, 2013, 12:04:25 PM
'Red69' and I worked out a deal, so that he received my NOS chambered pipes, and I got something I needed for my late '69 Z28 (a very nice pair of GM resonators which late Z-cars received).   And the shipping worked great too, between Bama and Wash state, which is a marvel in itself!... Smiley   Since my original exhaust pipes were cut for headers, I need to find a good original pair of head pipes and I'd be set with all-factory original GM exhaust...  Smiley

PS.  Reading this old thread, someone asked why the '69 Camaro chambered exhaust had so much trouble meeting noise standards (in PA and maybe elsewhere?), whereas the mid year Corvettes seemed not to have as much problem and they use the same muffling technology.   I'd never considered that before, but  *Maybe* it had to do with the single point decibel meters, and both Camaro exhaust pipes coming out the rear, and the corvette having side exhaust (you really don't get the full effect from a single side or the back)... 
1350  Camaro Research Group Discussion / Maintenance / Re: Front Brake Hoses.. on: August 08, 2013, 08:32:54 PM
I've got 3 'older' cars which I purged, cleaned, changed all the rubber parts, and changed over to Dot5/Silicone fluid, the oldest 25 yrs ago (a '69 Corvette).  The other cars are a '60 Corvette, and a '57 Bel Air.   No brake problems since with any of them, even though they sit most of the time.   I've recently gone thru the Camaro's brakes the same way, and installed silicone fluid in it, although it has not been driven as yet.  For someone who has many cars, which sit more than they are driven, I strongly recommend silicone fluid to reduce costs and effort in keeping your cars maintained.   If I only had a single car, which I drove often, then perhaps I'd make a different choice, but I'm not sure.
