Early/mid February. Engine build/car build was running pretty close in the early '69 production days, seems to average 1-2 weeks prior to car build in January - February. Post the VIN and it will help bracket the date -

My concern is the damage these misrepresentations due to our hobby - I guess there is nothing that can keep people from believing what they see as being correct, at least in their minds. Really a shame, but like anything else, it's "buyer beware" - whoever is top bidder on this car is going to have to work hard to get this thing turned into an original car. Probably gets a shock if and when he tries to sell it -

A challenge - by my count 28 separate incorrect details with this car, minor to major. groups to individual details. The laundry list is large - how many can exist on the same vehicle ? I love the statement 'got the car from a old buddy who told him it was a real Z'. At least the seller asks you to make your own determination or interpretation of originality - and it's already bid to $19K. I'm in the wrong business - I should be selling F1's for a living - but I couldn't get past the obvious.

As always, my own opinions -

319  Camaro Research Group Discussion / General Discussion / Re: Muncie question M20 and M21 on: March 01, 2013, 05:45:46 PM
Best reason to use the close ratio is to keep the rpm's up in the power band in between shifts, especially using a 4:10 and up rear, but they work well with the 3.73's ( that's what my '68 has as a combination, my '69 is a 4.10, l78 is a 4.10). To answer your other question, you can sneak up on an input and a cluster gear sometimes fairly priced, or you can buy a new set (Italian built, I believe) for a nice higher price. Add the cost of a rebuild kit ($150.00 or so), and you have a good freshened M21.

Gary,

Why not replace the input and cluster gear ? That's the only difference in the M20/21 - a lot cheaper than trying to track down another M21 (and one without a VIN like your case is -). Does it work (date-wise) for your car ?

Steve

I don't doubt it.

Good thing both of my Z's have good ones. I'm using the repop plate on the 4346 build - it started as a center section only anyway, and visually it looks pretty good. I need to check out the part number cast on the throttle plate to see if it matches the Holley parts listing I have. You do have to look pretty darn close to see the differences -

Steve

"3496" should equate to the 349th day of '86, M6 on the box is probably December '86. Stored in the house since purchase, taking up space in my office until I finally decided to make the swap -

Found it -
324  Camaro Research Group Discussion / Originality / Re: 4053 Carb question. on: February 27, 2013, 08:46:15 PM
Gary,

I bought mine from Music City Rod Shop in Nashville sometime in the early to mid 80's - whenever I first saw them advertised by Holley as reproduction carbs. Strangest thing about it - carb was stamped 3923289 on the air horn, but did not have the DZ stamp. 4 digit date code (I'll see if I still have the pics when I sold it a few months back), but everything else, from the screws to the bowls, throttle linkage, choke plate and casting marks, is as you see it in the pics - dead on. The only differences were as I noted last night - throttle plate is slightly different, dashpot is straight. Everything else looks good (color is a little golden over the original greenish gold anodizing), plus the metering blocks are correct and marked for the 4346 L78 carb, which differs only in the vented fuel bowl that I can see. I'll check to see if I can find the date pics of the service carb.

Regards,
Steve

Gary,

5583 and 4519 on all of them. Including the service carb. 4346 - 375 horse carb takes the same ones - that's why I parted it out.

Steve

Gary,

Check some of these out. In comparing the 2-1/2 carbs I have, the only differences I see are the dashpot bib and some minute differences in the throttle plate casting. At least for the one repop that i bought, literally everything else on the carb, from the bowls to the screws to lettering, was right on to the point where it is virtually impossible to tell at a glance which is which, with the obvious differences in cleanliness and colors/coatings. The only skew to this may be the fact that I bought this 4053 clone in the 80's, when Holley first released the remakes - later production might have changed somewhat.
Incidentally, the screw heads on the repop were identical to the originals, and the bowls (all) have sight plugs in them. If you need additional details let me know and I'll show you whatever you need to look at. BTW - 1 is an April '68 (June '68 Z), and 1 is a December '68 (January '69 Z).

Regards,
Steve

Post Script: Was your Z ever in Tennessee ? I looked at an unrestored Cortez X33 years ago, offered to trade my LS5 '70 for it (he turned it down, wanted $16K for the car). Stupid of me -

Give me a couple of days to fish them out, and I'll be glad to share pics of 2 original 4053's, 1-68, 1-69, plus the balance of parts from an early Holley 4053 reproduction I parted out (bought the carb in the 80's when they first started repopping them, sold the center section, 4 digit date, and kept the bowls, throttle plate, metering blocks, and all small parts intact to rebuild my 4346 for the 375 horse).

I really wish the Holley Custom Shop was still in Springfield, TN - they used to take your Holley in, completely rebuild it, replace any and all worn parts with new (proper part #'s !), restore and replate ones they didn't have, and bench it and send it back to you for about $400.00. I don't know if they still offer that service, but it was great while it lasted here. They closed that location down, moved it back to Bowling Green years back.

Regards,
Steve

PS.  Are you in Murfreesboro?  I'm just north of Huntsville;  we should try to get together sometime... compare notes!

Gary,

North and east of Murfboro about 30 miles - shame our local Camaro club went away; we used to have some great outings and meetings, local drive-ins and events. Maybe we'll get the chance to meet at one of the local shows -

Keep the posts coming - it really is goading me into working on the projects.

Regards,
Steve
