16  Camaro Research Group Discussion / Originality / Re: Canadian Emissions / Smog on: January 09, 2014, 05:01:03 PM
I have 2 Canadian GM Vintage Vehicle Documents for 1968 Camaros, both 396/375HP cars and 1 has KD1 code which is smog exempt (delete) and the other does not. The cars are about 3 weeks apart. The non smog equipped car was sold new at Beny Chev Olds in Lethbridge/Alberta/Canada in March/68, the other with smog equipment was sold at Stedelbauer in Edmonton/Alberta/Canada in Feb/68. 

My own 06A RSZ28 has smog and was delivered to Beny Chev Olds in Lethbridge/Alberta/Canada,

1969 Canadian cars had smog unless the GM Documents showed KD1, which was smog delete, this might only apply to solid lifter cars. I think there was like a $17 credit if the guy ordering the car was savy enough to list RPO KD1, this was only to Canadian delivered cars not USA.

Here is my 9-E-23, still has the CZ ink stamp, 100% ORIGINAL for sure, have owned this Z28 since 1974. Its kinda scratched up from some ham fisted morron using a pry bar to tighten the belt, it still has the dated diodes and has never been apart. The 00 is faint on it too, as well as the 7 on the stamp.

weren't some smog pulleys 'phosphated'?   I think Jerry's book also says that...??   

My 06A Z28 smog pulley is phosphated, its original
19  Camaro Research Group Discussion / Originality / Re: 4053 Carb question. on: May 23, 2013, 10:56:35 AM
FWIW, and JMO but Personally I have never seen a "Known Original" Holley 4053, 4346,  2818, 3246, 3247 etc., pre 1972 Holley carb that did not have the clutch head housing and screws. The later hsg with the Phillips screws shows up a lot on service dated or "restored" carbs from well known carb restoration company's for some reason. The early accelerator pump housings are very prone to bending/warping from over tightening as well as engine heat.

BTW I have been rebuilding/restoring carbs for 45 yrs., so I have seen lots.

As noted, I have changed lots of lowers, but as a rule the uppers last a lot longer. If you feel like you want new ones, then use the Heratbeat ball joints, they are close enough for what you are doing IMO.
 BTW riveting them in is not that hard, if you don't want to tackle it, take them to a big rig truck shop, they will have a rivit press and the tools.

I have never seen the white 70 switch on 69, A friend has a 11B/69 and it has the metal switch like below.
22  Camaro Research Group Discussion / Originality / Re: Owner's Manual - 3rd Edition, 1969 on: May 13, 2013, 09:35:41 PM
It is Important to note - That Canadian Delivered Cars used a different manual, they had a Red Front Cover instead of Blue, and they dont contain the Helm pages.

24  Camaro Research Group Discussion / Originality / Re: Battery Side post or top question on: April 20, 2013, 08:56:09 AM

My 06A RSZ28 has the original side post cables, it was made approx June 20, shipped June 23, ( Canadian Documentation). All June cars are 06A BTW. The original battery was a Y77 with different size terminal threads. My car had the original battery when I bought it, it has a Delco Replacement and I had to change 1 attachment bolt. I have a NOS Y77 battery for future use.

25  Camaro Research Group Discussion / Decoding/Numbers / Re: What carb date for my 06A early June Z on: April 15, 2013, 11:14:02 PM
Those are the "correct missing choke parts"
Accelerator Pump housing looks like it has clutch screws, and the baseplate is the original unreinforced line installed. The choke pull off has been changed at 1 time as it appears to be a straight nipple. Original 4053 has a small bend in the nipple where the vacumn line pushed on. No Big Deal.
26  Camaro Research Group Discussion / Decoding/Numbers / Re: What carb date for my 06A early June Z on: April 15, 2013, 05:38:54 PM
If I was to look for those parts would they be hard to find? I have 5 sheets a friend gave me in 1975 from a HOLLEY CARBURETION VARIABLE SPECIFICATIONS AND PARTS counter book , page 81 and 82 showing the 4053 carb numbers, page 240 that has the exploded view of the 4150 TYPICAL VIEW ILLUSTRATION NO 34-1, page 241, 243 with part names and index numbers.

Fast idle cam is (136)41R-539 and the fast idle lever is (6)4R-852. The missing screw is not found. Just wondering if if I should waste my time on this or let it go.

Al at Chicago Corvette will have those parts, but they are probably expensive. I was reading the sellers reply, he doesnt have a clue what he is talking about, they dont use a screw for the fast idle, the missing lever has a tang that is bent/adjusted to set the fast idle on the Fast Idle cam steps. They are not $10. You should insist he post a picture of the drivers side of the carb, as well as a under neath shot, its no trouble to add pictures, if he doesnt want to comply dont bid. I have seen many DZ carbs with the later issue reinforced baseplate, (originals were prone to breaking on the LR corner) plus the wrong accelerator pump housing and lever, originals use clutch screws., plus ask him the secondary metering block number, it should be 4519

Once again engines were furnished to the assembly plants without carb. The inventory of carbs was there, not at Flint so the carb date is unrelated to when the engine was built.

There are 30-40 known build dates for 4053 carbs covering the 1969 model year. That means they were batch-built 400-500 units at a time. As a Tier 1 supplier there is no way carbs were 'made to order'; they were shipped from finished goods inventory. They sat in stock at Holley; they sat in stock at the plant. There was no first-in first-out requirement. If it was the correct part it was used regardless of date. My data shows 943 carbs as late as August '69.


Thanks. Good point.  That may be the case but I posted my carb date/engine build date as a reference so comparisons could be made. I understand that carbs were probably not rotated like groceries with pull dates, and a wider date range is known to exist. The Ebay 4053 Mar 2 week carb in question could probably work for Gary, but seeing as the posted 05E Z28 1,000 serial numbers less has a April 3 week carb, do you think that would be considered normal?
28  Camaro Research Group Discussion / Decoding/Numbers / Re: What carb date for my 06A early June Z on: April 14, 2013, 07:23:25 PM
Thanks fellas. I am thinking of putting in a bid for this carb. What do you think? I'm really looking for a 943 but haven't found a core yet in 14 years of looking. Everyone wants to sell me a restored one and I don't want a restored one. I want the patina to match what I have.

IMO it is TOO EARLY, (Read my post above, my carb is 9-5-2 and my DZ engine stamp is before yours), I honestly don't see how a March carb can find its way onto a June car, 2 weeks to 4 weeks is the norm, with 4 even being a stretch.

Seller says - " very nice and the factory choke set up work perfect too",    I don't see how that is possible, it is missing the fast idle Lever and Plastic Fast Idle Cam. You should ask him for a picture of the LH rear drivers corner to see if it has the original non reinforced base plate.

V0604DZ cast date on block is E 28 9 heads are E 28 9 and F 1 9

What is your engine assembly date?

My 06A Z28 ( owned since 73) has the original carb 100% for sure, my engine is VO527DZ and my carb is 9-5-2 ( May 2 week)

Slots on the AD wheels are the same big slots and irregular corners same as original YH wheels.
