Hi Zedyone - -WOW! "Subsystem Manager for Propulsion” on the Artemis Crew module (that is still Orion right?) . Congratulations: that is a huge vote of confidence from both your Technical and Management chains. I’m sure you will do an outstanding job. (although it can come with an increased level of stress). Also great write-up on keeping that 53 year old Z on the road. Lots of useful information there for all of us.

Another link - some amazing Z's... https://www.mecum.com/videos/the-st-yves-datsun-nissan-collection-mecum-kissimmee-2024/?fbclid=IwAR0QDyChMOcEkXUzE7oQyUJQH6eceyWdy7AohIJ8Du-73GRTBOiPmWHjfe8

Any known history? Carl

That is a very strong offer - and looking forward I don't see the market getting stronger any time soon.

Has anyone been watching Hagerty Auctions? https://www.hagerty.com/marketplace/auction/hGKn8rHytYkjYUULAJlnh?fbclid=IwAR0MD8_76rmoDK-kIyAPyuPwq4adRbQQ1efNcrX70h6a0GXZ9meozisyOgQ

A 1972 sold for $25,500.00 on BAT - in better shape - although it is an A/T. This 71 is going to need a repaint and new Dash, seats etc. etc... In todays market I'd say this 71 should be closer to the $18K to $20K range. 18 months ago it would have been snapped up at $25K... not today... https://bringatrailer.com/listing/1972-datsun-240z-283/

You could have bought it last week - https://bringatrailer.com/listing/1974-datsun-260z-race-car/

EBay - 22 Oct. 2022 - - asking $149,000.00 bid to $50K RNM Actually looks pretty nice - just non-numbers matching...

Hi Roo Question: - - 58.674 bhp - - per what? What is "aero power" or how does that relate to engine HP? thanks, Carl

I believe that they caused vibrations only in a specific RPM range - AIR the test team driver said he needed to maintain a certain specific higher speed range long enough for the vibration to show up and get worse. Slower or faster was not a problem.

Hi Kats: As I understand it: GT Class is Grand Touring Sports Class “F” Engine Size is: 123 CID (2015.61cc) to 183 CID (2998.83 cc) 152.134 mph 1972 (L24 BRE Front Spook and Rear Spoiler) 166.037 mph 1976 (L28 G Nose with chin spoiler) 168.721 mph 1985 (308QV Ferrari) 172.974 mph 2010 (L28 - Rebello 3.0L - slight body rake) Between 152 mph and 166 mph two things changed. 1) L24 to L28 and 2) BRE/Spook/spoiler changed to G Nose. I have to think that the L28 accounted for the additional speed. A Wild Guess - about setting the Z on blocks: There could be a significant difference between the Wind Tunnel in Japan 1971 and the one used by HybridZ in 2008 was it? The Wind Tunnel in Japan may have had a limited number of sensors spaced in the floor - so the Z there was set on blocks - on the sensors. The Wind Tunnel used by HybridZ has sensors more easily movable / or more of them in the floor - so the tires could set directly on them.

@SpeedRooThanks - the old links in my bookmarks wouldn't load.... so I used the image I had saved at the time.

THANKS - Last sold on BAT - 15 July 2023 for $39,250.00.

Wonder what the VIN is on that 73.

The test data from HybridZ... the numbers for a stock Z (test #2) Cd /CL etc are pretty close to what Kats Posted.

With the rust in the roof and the patched-up floorboards - given the last two or thee months of market pricing - I was surprised it sold for over $18K.

OOps.. MY Bad! Thanks for the correction - 03 it would be..

Per the TSB - the change over from Yellow to White was at HLS30 31643. That would have been an 05/71 Date of Mfg.

This "seems" like it would be a reasonable buy - if you are close it might be worth taking a look. https://www.ebay.com/itm/325567090216

It is a lot of money for the school and a little bit for the Datsun. Several people contributed directly to the school as well.

The VIN stamped on the Firewall was HLS30 14160 - The first series of chassis serial numbers ran up at least HLS30 20533. The second series of chassis serial numbers (aka Series II) started at HLS30 21001.

Sounds like we had similar experiences during the 73 Model Year. I was the New Car Sales Manager at Jaremko Motors in Spokane, Washington. Far too many very unhappy Z Car Customers ! I moved from Washington State to Florida in 1974 and worked at Clearwater Datsun / BMW. Bobby Clark the Dealership Manager was also a Racer. Clearwater Datsun installed the Hood Scoop on two 240Z’s that I knew of. Related to the problems with the 73/74 Flat Top Carbs, Mr Uemura writes in his book; "DATSUN 240Z Engineering Development" https://www.lulu.com/search?adult_audience_rating=00&page=1&pageSize=10&q=Datsun+240Z "Executive Director Ryoichi Nakagawa, the chief of the engine departments, gave us a pep talk, saying, “In a car, the worst case that can happen with this defect is the engine stalling, but if this happens on a plane, it crashes.” Although the engine design departments also tackled countermeasures, satisfactory results were not obtained, and the manager Harada of the Third Design Department asked us to cooperate in coming up with countermeasures for the vehicle itself. As a temporary measure, a heat shield plate was placed between the exhaust system and the carburetor, glass fiber was wrapped around the fuel system pipe, and louvers were cut in the engine hood to vent heat. But this was not enough. Then, as the last resort, a powerful sirocco fan, which began to turn when the temperature in the engine room rose above a given temperature, was installed in the engine room to pump out the heat. This almost solved the problem, but it was never perfect, because the fan would turn for a while or sometimes started turning suddenly even after the engine was turned off, surprising drivers. Assistant Department Manager Shidei, who was the chief engineer at this time, visited America to persuade Nissan Motor Corporation U.S.A., to deal with the problem using this tentative measure for a while until a proper countermeasure could be taken. I can’t imagine that would have been an easy task for him. One year later, we solved the problem properly by abolishing the carburetor and adopting the L28 engine with electronic fuel injection."

A year and a half ago - this would have been at least $45K to $48K. At $37K the Buyer got a great DEAL IMHO.
