Looks like it has an N42 intake manifold without the egr like '76 and '75s but the fuel rail looks to be '78. Also looks like a ZX head with the electrical plug above the dipstick between #6 & #5 plugs.

That's what I probably would do too. I think I'd try to figure out where the broken off metal is located now. Being it's exhaust it's probably down in the exhaust manifold? You can buy those bore scopes that use your smartphone as the monitor if you're a worrier. It seems impossible to go backwards and get in the cylinder, but the damndest things happen when you're not expecting it.

This might be helpful. https://www.atlanticz.ca/zclub/techtips/EFI&fuel.htm I bought a '76 that would crank and idle but wouldn't take fuel. $1,000 for a perfect car with faded paint and carpet that had a spider web on the sweeper vain. Cleaned that and ran like new.

I've got my 9/76 n47 bare bones. I've removed the valve train but I'm sure the liners are good. I'd let it go for next to nothing. I can get some pics over the weekend after I remove the contents of my storage building. It's in the way back section. I've got 6 heads and 2 Zs.

You could try that junkyard search engine and see if there's a p79 close by. The n47 is the least desirable head. Mine had a spray bar and an oiler cam, 0 oil pressure. I robbed the valve train components and scrapped the aluminum head.

I've always read it's not a good move to remove. Here's some threads on them. https://www.google.com/search?q=removing+exhaust+liners+n47+classiczcars.com+&client=ms-android-americamovil-us-revc&source=android-home&source=hp&ei=siN5ZKrvMZzcptQPmryb0AE&oq=removing+exhaust+liners+n47+classiczcars.com+&gs_lcp=ChFtb2JpbGUtZ3dzLXdpei1ocBADMgUIIRCgATIFCCEQqwI6CAgAEIAEELEDOgsILhCKBRCxAxCDAToLCC4QgAQQxwEQ0QM6CwguEIAEELEDEIMBOhEILhCABBCxAxCDARDHARDRAzoOCC4QgAQQsQMQxwEQ0QM6EQguEIMBEMcBELEDENEDEIAEOgsIABCABBCxAxCDAToFCAAQgAQ6CAguEIAEELEDOg4IABCABBCxAxCDARDJAzoICAAQgAQQkgM6CAgAEIoFEJIDOggIABCKBRCxAzoGCAAQFhAeOggIABAWEB4QDzoICCEQFhAeEB06CgghEBYQHhAPEB06CQgAEBYQHhCLAzoLCAAQFhAeEA8QiwM6CwgAEIoFEIYDEIsDOggIABCJBRCiBDoFCAAQogRQxw9YtbgBYP7CAWgBcAB4AIAB6QGIAeIpkgEGMC4yOC40mAEAoAEBsAEAuAEC&sclient=mobile-gws-wiz-hp

Yes you can see the difference in color. The old ones are darker. Here's a good picture from @heyitsrama

My n42 had bronze seats. The n47 on my 9/76 build date 1977 has steel seats.

If you replace the head gasket it'd be a chance to pull the front cover off and check the timing chain and guides, tensioner too. Maybe a new water pump since they're available and not very much money. Check the rubber on the motor mounts in the engine bay. Those are fairly cheap too.

I found the right size low pressure fuel rated hose for my vent lines at a local O'Reilly parts store. Seems like 5/8" was the larger size and they had it. Used two 90 degree brass 3/4" PEX for the 180 degree bend. Saved a lot of money and nobody knows but us.

I've learned something very important about end of life. People need closure even it's just a minute or 2. My guy was abducted it feels like and it still bothers me. I can't imagine how his wife and kids feel. Thank you all for your kindness towards me. It has always been comforting to be accepted by smart, thoughtful people that make this forum special to me.

Hey all. The guy I worked for off and on, presently on at the time, past away in his sleep at the end of January. I've gone from a great 30 hour a week job to 55 hours a week by myself running a paint store. He had that and was a general contractor plus 88 two bedroom apartments plus another 10 or so commercial rentals. We lost our best employee when he didn't wake up one morning so I'm trying to help his family which he kept out of his businesses as best he could. I read the site every day but can't reply too much because of how busy day to day is. Making a lot of money is my get out of bed every morning motivation and his family is my family too. Saving up to do things in the future. That P90 head is my next project. I miss participating and chatting with the forum members but I must help the family get all his finances in order. He was a private guy that wouldn't worry us with the behind the scenes going ons. I'll be more active asap. Cliff

With those high values a guy could go sideways and commit insurance fraud. Instead of "Bring a Trailer" it'd be "Bring a Shipping Container" www.basc.com.

I have Hagerty for my Zs. $40,000 agreed value on my '72. $10,000 agreed on my '77. This year's price was $191 up from $189 last year. A guy came up from Birmingham and valued the cars, took pics of the garage and the locks on the doors. Hard to beat their coverage, prices. I think I have 3 free flatbed tows a year. 3,000 miles a year per car max. I put maybe 500 on the 240 a year so I've built up an extra 10,000 if I decide to drive Route 66 a few times. Get YOM (year of manufacture) tags if your state allows. You pay once and that's it. Here's my '72 with YOM tag.

Nice tshirts. I stayed on bat.com for an hour after looking at that. Z prices are low too, in my opinion. Good time to buy if you're able.

I put a new one on my 280 using the old one to drive it down on the collar. It has a noise. I had one pressed on the 240's collar. Crickets...

Well that's the reason I run high octane pump gas. My car sits for a month or so but when I finally have time for an early morning cruise through my close proximity "loop" I stop and add fresh 93 octane to perk the old gas up. So far so good but I do have a high end flutter. Tomorrow morning I'm going to drive it and see if I can nail it down. Please stay tuned....I'll most likely need your help. 🥰

What's your thinking on cars that stay in the garage mostly? I know people reccomended adding octane boost for cars that sit for awhile between driving. I've gone on the idea of more octane fuel added would kind of keep me on plane with additives without the exta effort but I learn something everytime I read classiczcars.com.

I filled my '72 until it dripped from the fill hole. They possibly filled it into the vent hole if they couldn't get the fill hole plug loose and out. I've read that before.

I'm good now too! Thanks Mike.

Once you click one it stays for a very long time. I'm always signed on to classiczcars.com so I don't have issues unless I'm on my desktop at work which I never log on. So I see your glitches too Zed Head when I'm at work.

If he sees this @djwarner will now something. He had an auto.

I used to put a spare behind the tag, on one of the tag fastener screws/bolts. Then I found out that was everyone's secret hide. Now I have them zip tied on the rear frame behind the rear tire. BTW, my USA '72 does not have the spare key spot we're talking about.

Seems like there's a rod with cotter pin that goes to auto transmission you could unhook and try and move the selector to neutral. I've seen that somewhere before, not positive it's a Z thing. Hopefully it's just stuck drums.
