Originality / Re: 1968 Z28 smog pump assembly
« on: December 13, 2018, 04:46:55 AM »
For some odd reason, the phone and computer are not speaking to each other tonight, so no pics yet. The spacer is definitely steel, about .750" or so, recess on the bottom to accept the pump pilot, piloted on the top side for the pulley. Pump is dated 290/7, Whittek clamps are 3/7, so the assembly is a bit early, but still for a '68.

Thanks to advice and research from rare396bronze (who found the spacer listed for a '68 Vette 327 application), I believe it's most likely a Corvette early takeoff. Jerry's Definitive 67-68 chart of smog equipment shows multiple applications for the DH diverter: even though the numbers are good, it also has a black relief valve mounted in the pump body, accurate for Vette (but should be green for the Camaro according to McNeish).

Best thing I can picture at this point is to keep my eyes peeled for a 522 pulley, plus then decide how to get this one gutted without endangering the shape it's in.

Originality / 1968 Z28 smog pump assembly
« on: December 12, 2018, 12:57:41 AM »
1968 Z28 Camaro fiends,

I have a complete 1968 smog pump/diverter assembly that includes a spacer between the pulley and the pump. It's perplexing, as this pump/DH diverter/bracket/hoses/Whittek clamps/fittings appears to have never been apart, very pristine and dated correctly, with the exception it has a "116" lo-po pulley instead of the "522" deep groove, and it has a spacer between the pump fan and the pulley. I've read in at least one back thread about the possibility of an occasional "116" pulley making it on to a Z (parts shortage on the line ?), but my real question concerns the spacer. Considering the lower performance V8 water pumps were shorter as compared to the "326" Z water pump, did the "taller" Z water pump require the spacer (either pulley) ? I cannot find any reference in the assembly manual to a spacer on any 1968 application - hence the question.

Regards,
Steve

Comes right off - done it a couple of times on my Z11 (taking pics of the A/C valve and bulkhead underneath the cowl).

I don't know to many guys who would admit to owning a citation let alone ordering one...

I had a black '80 as a company vehicle, grey cloth interior. I think it was my first front wheel drive car, to be exact. Preceded by a '78 Malibu, followed by an '83 Caprice. First V6 I ever drove, as well.

Steve

What's your opinion on the attached pic ? Looks pretty close to me -

Chick, I wish you would stop that. I've got enough depression with the winter and the holidays going on than to have you remind me of perfection - lol.

Thanks Steve, do your letters and numbers measure roughly 3/16"?
This hose is from line to pump?
Anyone else have their original hoses?
Thanks, Doc.

Doc,

Yes, this is the frame line to pump hose, The "GM" seems a little larger than the balance of the markings, measures almost .250", the rest are right at 3/16" best I can scale them. The square is about the same as the GM logo -

I've noticed the reproductions have several additional markings that the original don't have. I replaced mine with Goodyear fuel lines (but I don't see concours judging in my Z11's future.

Regards,
Steve

Here's mine, from my 03D Z11. Kinda faint, dated 11/28/8. Not ribbed, but "textured" with the reinforcing plys noticeable -

James - yours is pristine compared to mine. Amazing construction (from the U.S. of A !) to last this long.

Laugh now, DW - you'll be there in 50 years or so !

These things are tough to get a decent pic of, but hopefully they show enough detail. The "fuzzy" material is pretty coarse, almost like a loop pile. You can see from the end-on shot that the cross section is round, not flat. The tabs on the back are quite small, very bendable.
No chrome or stainless bead like the '69's, obviously.

Regards,
Steve

If I can brave the cold tonight I'll retrieve my NOS set from the deep freeze garage and take a few pics. My old bones have a hard time adjusting, so give me a bit -

I put that piece of tape there :-)
I heard from some other CA friends Charlie you were hanging around the car after hours. Good one! LOL
Here is the piece of tape I somehow missed after how many times of cleaning, etc.




YOU HAVE TO BE KIDDING. If that's all the judges could find wrong, I'd consider the car a perfect 1000 point car.

Great work -

Decoding/Numbers / Re: 1967 Z28 Engine and Transmission Stamps
« on: November 28, 2018, 04:39:01 AM »
Engine pad needs to be clean (no paint) in order for it to be fully accessed.

Agreed. Font and general stamping looks good to me, would be more certain if you could see the actual pad surface. I've seen the offset suffix before, suggests a separate stamping event during final assembly.

If Jon Mello knows it, I believe it.

Thanks,
Steve

Hey DW,

We talked to the guy that has this car back during the Feb. swap meet, seems like they acquired the car late last year. It's as described to me at that point - must have finally been considered an overwhelming project. Shame it deteriorated so far before they bought it - car is from Ohio, so you can allow for the salt damage. Rust doesn't discriminate -

Regards,
Steve

General Discussion / Re: Not sure where this should be posted
« on: November 26, 2018, 01:20:26 AM »
In my opinion. broaching the deck surface instead of face milling probably has quite a bit to do with the inconsistency of the deck as far as flatness and surface finish are concerned. I've sold to and serviced several engine manufacturers in the area (GM, Nissan, Hyundai) - modern aluminum engine block machining generally (but not always) utilizes large diameters face mills, up to 400 mm, using mostly PCD inserts with wipers - flatness and surface finish are held to very tight tolerances. Most blocks have cast iron liners, so the mill has a bimetallic surface to contend with (some are cast in place, others are frozen and "dropped" in; they require decking to finish). All of the processes add up to why modern engines can last so much longer with decent maintenance than our good ole small and big blocks used to (metallurgy has advanced a lot to boot).

All that said, it makes you wonder where we would be by now if we had the engine and fuel management technologies prior to the horrendous '74 and later emissions dogs. But i'll still stick to my 302's, 350 and 396 equipped cars, any day.

Steve

This has been discussed a lot on the forum - including comparing differences between Dynacorn, AMD, Goodmark, Heartbeat, and a lot of worse stuff. I found many threads, including this one from 2012 that has had a lot of views. I'm not trying to promote any one manufacturer or retailer, the statement I made was my own opinion -

http://www.camaros.org/forum/index.php?topic=9964.msg73338#msg73338

I've owned three sets of factory GM quarters, still have the first set from 1978 that I bought from GM. I don't think I'd hesitate to drive to Buford and pick up a set from AMD, as the quality I've seen from them is very good. Again, just my opinion.

Regards,
Steve
