Zed Head

Looks like the NA 280ZX engine might be 79 or 80. Can't see the cylinder head temperature sensor. But that's USA only, seller might be in Canada or Europe or Australia. N42 block, N47 head, probably. They all look complete. Even the fan belts and motor mounts are still attached. Shipping could be expensive.

Whatever you're writing in your messages must be something he's avoiding. You seem reasonable and rational on this forum. Any reason he would be avoiding you? Not a good look for him if there's no good reason. Maybe your messages aren't getting through. Never know. This should bring him directly to this thread. Good luck. @Sean Dezart

If I was trying to sell them I'd supply mileage when removed, how well they ran, and the price. I assume that maybe you're just looking for offers? Good luck.

Aside from replacing a part that meets Nissan specs, another factor to consider might be that used Nissan is probably better than new aftermarket.

How much? Did you see them run or are you passing on information?

Sample size cannot get any smaller. I doubt that that's why they come out since the the space between the rocker arm and the valve/pad assembly would have to open up enough to allow the lash pad to pop out. No logical reason for the divot to stop that from happening. Besides the fact that many people have had that happen when they restart old factory stock engines that have been sitting for a while. Most people think it's caused by sticking valves. Maybe your guy sets his guide clearances too tight. But, he's the builder. Good luck.

I saw him posting some comments on BaT. Probably breaking a BaT rule but you could comment in one of the auctions that he comments in, with an @. Scroll down and you'll see his comments. https://bringatrailer.com/member/seandezart/

Also should note that it's called several different things around the internet. Valve guide, Guide - Rocker Valve, lash pad. Might help for searching. The part number works well though.

Here's some stuff. Not sure if they're showing the -Y7000 pads (Replaced By:) or the original part number. https://www.carpartsmanual.com/datsun/Z-1969-1978/engine-280z/camshaft-valve-mechanism/25 https://www.nissanpartsdeal.com/parts/nissan-valve-guide~13218-a3501.html

Like these? What kind of problems has your machinist had with the flat bottomed pads? Not sure that the dimpled ones are actually "stock type" for an L28. Don't know. https://jdm-car-parts.com/products/kameari-performance-valve-lash-pads-for-nissan-l-engine https://datnissparts.com/stock-thickness-120-lash-pads-datsun-nissan-l4-l6-l16-l18-l20a-l20b-l24-l26-l28-13218-y7000/

Not bad for 1976 280Z survivor. Still has the splash shield and exhaust pipe heat shields. https://bringatrailer.com/listing/1976-datsun-280z-106/

So many new things pop up on the internet now it's a surprise they haven't interviewed his coworkers who saw it happen. I just read a different article yesterday about him where he said he thought he should have switched to being a normal right-handed player. He started playing leftie, like Jimi Hendrix, and didn't think he could relearn everything so he just improvised with those prosthetic finger tips. I worked with a guy years ago, after his own accident, who did similar but cut off about half of all four. Said he didn't feel a thing, they were just gone. Metal shears are dangerous.

Might as well do the whole album. Had it on cassette (high tech for cars!) back in high school. Did not help my studies...

No reserve 10/70 1971 240Z project in Texas. https://bringatrailer.com/listing/1972-datsun-240z-359/

Well, this is a bummer for the day. https://apnews.com/article/ozzy-osbourne-dies-adff88b55f1d3b0bace5705d58d3cdde

I never realized that David Cassidy turned in to a global phenom.

Interesting beetle frenzy mania going on. Almost like a whole different brand of car. https://bringatrailer.com/listing/1973-datsun-240z-290/

Spooky scary Saturday night space music.

I got curious so I looked in the GI pages of the FSM's. 1972 seems to be the first time they describe the stamping of the identification number on the firewall (cowl). 1970 and 71 don't mention it, that I can find. 1970

is killing me.

It seems reasonable that Nissan might have started with engraving then moved to stamping. Or maybe somebody can show or explain why the engraving looks like stamping. That would be the most helpful. For people who have actually seen both and understand the processes. Engraving removes metal. Stamping displaces it.

I've wondered about the stamping/engraving. As somebody who has worked with both stamping and engraving, it's incredible to me how Nissan was able to make engraving look like stamping back in the 70's. I assume that they used a pantograph to get the precision. No way that it was done free hand. Also odd that a pantograph can't hold a straight line. It would be very cool to see some of the tools they used back then. https://www.hotrod.com/how-to/where-is-the-vin-number-on-a-car

I was going to post the Cream version but went a little farther back. People are digging up these old recordings all over the place. Pretty amazing.

The well-traveled 71 only got $12,500. https://bringatrailer.com/listing/1971-datsun-240z-324/

Yeah, the pictures were about the wheel positions. I mean, the seller put them right out there for everyone to see. Still got $31,000. Not bad for what looks like a car that might have smacked a curb or something.
