1  Camaro Research Group Discussion / Mild Modifications / Hub Centric Adapters on: December 26, 2014, 04:13:30 PM
I read the earlier thread about mounting Torque Thrust II's on a 67 z/28 but no source for adapters was given. I my case I have a 69 Z with TTII's made in the mid 90's. I've tried the use of conical lug nuts to achieve a better concentric fit and then switch over to the long necked lug nuts but it's quite hard to repeat that successfully. I've contacted numerous Wheel/Tire stores but no one (not even American Racing) offers concentric adapters for my wheels and car. My measurements indicate a 70.5mm ID with a 85.5mm OD and .25inch thick would be good. It seems that I'll have to have custom ones made, but before I do that I thought I'd ask this august body for any other suggestions. BTW, the tires and wheels have been professionally balanced and checked for roundness and that helped but just not enough. Up to 60 mph all is ok, but after that the vibration get's obnoxious. I also tried original YH wheels that when installed work perfectly. Thanks.  Smiley
2  Camaro Research Group Discussion / Decoding/Numbers / Re: 69' Z/28 on eBay, Has no Tach?? on: August 26, 2013, 07:00:21 PM
For what it's worth, I have an 1969 Z/28 without a factory tach. It also has no console. Also have the chassis broadcast sheet, actually only about 60% of it has survived life under the back seat. The car is an 05A car built in LA. I've talked to the original selling dealer who confirmed for me that they typically ordered Z's for inventory as cheaply as possible thus my car came without most options.
3  Camaro Research Group Discussion / Decoding/Numbers / cam ID help on: June 08, 2012, 03:01:22 PM
I'm disassembling a 350 I've had in a bag for about 12 years. The motor has previously been rebuilt but had less than 1000 miles before I got it. The cam is a flat tappet hydraulic. Can anyone identify this cam? Cast into it are "I7  04" "1578 D8" and stamped into the end is "1944 0". There is yellow paint on part of the core diameter. Thanks.

Count me in for two.
5  Camaro Research Group Discussion / Restoration / Re: Broadcast sheet restoration on: April 21, 2012, 12:38:20 PM
I've tried to attach a photo I took in 2006 showing the sheet in readable condition, and one taken today (4/21/12). They look quite similar though by January of this year the actual sheet had darkened considerably from the 2006 photo. I didn't take a pic of the January condition, but it worried me enough that I had the "conservation process" performed. The car has been restored to original condition per the broadcast sheet with some details awaiting funds and discovery of correct parts. When I bought the car in 1995 or 6, it was in sad condition with lots of stuff missing. Fortunately, it had not been cut up though it had been in at least one serious wreck. The ownership history shows the car spent its entire life in the greater Portland area. I used NOS or reconditioned original and dated parts to reconstruct it and did much of the work myself. I live in Aloha, Oregon a western suburb of Portland.

To complete this story, I had Elizabeth Chambers, a document conservator with the Portland Art Museum, clean and preserve the brodcast sheet. Turned out well and cost $120. I learned about the damage acids from typical papers, envelopes and even photo storage sheets can do. So now the paperwork can survive another 50 years just like the car. Anyone needing similar document conservation in the Pacific Northwest should consider using Elizabeth. Her phone is 503-276-4216.
7  Camaro Research Group Discussion / Restoration / Broadcast sheet restoration on: March 20, 2012, 03:54:25 PM
I've decided that I need to get the chassis broadcast sheet restored for my 69 Z/28 before it becomes totally unreadable. I took pictures of it a few years ago but I'd like to get the real document restored. Any recommendations as to who to use? I've spoken to one possible source ACA Paper Restoration in Devon, PA. They claim to have done this a few times and suggested an approximate cost of $250. Thanks much.  Smiley
8  Camaro Research Group Discussion / General Discussion / DZ302 for sale on Craigslist on: November 09, 2011, 03:47:26 PM
Just exchanged emails with "Jay" regarding a motor he has for sale. He read the numbers off it to me and they aren't what I'm interest in but maybe someone here might be interested. Anyway, block is 3956618 dated B-17-9 and stamped V0220DZ. Vin is hard to read but looks to him like 3L?020220. Heads are 186's both dated B-11-9, Has 472 intake and 418 valve covers. he can be reached at or 360-580-7313 (Washington state). He's asking $5K the complete running motor.
9  Camaro Research Group Discussion / General Discussion / Re: Borg Warner T10 identification on: December 29, 2010, 01:38:18 PM
Thanks John. I presume from your answer that you can't tell which GM division made the car that this trans came out of.
10  Camaro Research Group Discussion / General Discussion / Borg Warner T10 identification on: December 28, 2010, 03:12:45 PM
I removed a T10 from my 1969 Z/28 when I bought it years ago and I finally decided to do something with it. Hope someone can help identify what it came in originally. The main case is marked "T10-1B", carries what I'm guessing is a date code of "G20-1" and is stamped "WE82-3" vertically behind the side cover. The input shaft is 10 splines with one groove while the output shaft is 16 splines. The tail shaft is dated 8-24-61. Thanks.
11  Camaro Research Group Discussion / Decoding/Numbers / Re: big block engine code deciphering on: July 30, 2009, 05:44:50 PM
It's a 2-bolt block like the picture you sent. BTW here's a picture I just took. What looks like a crack near the middle oil hole is actually just a cob web. Thanks for all the knowledge and support this site provides!
12  Camaro Research Group Discussion / Decoding/Numbers / Re: big block engine code deciphering on: July 29, 2009, 06:32:08 PM
Thanks. It very well might be a "Q" since the bottom part of the character is very faint. Also cast into the block near the oil filter and under the bell housing is "Pass High Perf". There appear to be oil fittings possibly for a remote cooler. Is this block cast any differently than the ones used in the cars?
13  Camaro Research Group Discussion / Decoding/Numbers / big block engine code deciphering on: July 28, 2009, 01:37:17 PM
In my swapping to procure parts for my 69Z I ended up with a big block but don't know what the code means. Hope someone can help. Casting number is 3955272, has two-bolt mains, casting date is April 24, 1969, front pad stamp is TO428YO. Thanks.
14  Camaro Research Group Discussion / Originality / 1969 door lock knobs on: May 26, 2009, 03:31:33 PM
Where the original door lock knobs for a 1969 LA-built standard coupe interior smooth or grooved on the outside of the shank and were they plastic or metal? Thanks.
15  Camaro Research Group Discussion / Originality / Re: 1969 exhaust question on: May 05, 2009, 03:10:03 PM
Hi William, you've been a wealth of information as has this entire site. Anyway, I have a 1969 Z/28, 05A Los Angeles build date from which I saved the chassis broadcast sheet (or most of it!). In box 198 I see the letters "FQ". Anything special you can tell me about the correct exhaust system it came with? Thanks.
