So I got a 240z and the engine was seized, I took it apart and now I have a 280z engine block/head all parts are in there and it's unseized, can I use all the other parts from my 240z engine like carbs and intake or are they not compatible with the head. Thanks

Water pump, distributor, core plug in head.  It's been taken apart and you have no idea how well it was re-assembled.  Looks like a pile of parts.

That is true, I plan on changing the gaskets anyway because the guy said they should be changed. I plan on looking inside with a boroscope camera before buying what should I look for in the head and in the cylinders

I'll try to be a bit more clear - I think that L28 engine is a pile of junk, that's probably only worth about $50.  You'd be much better off to look around and find a complete used L28 engine.  Or rebuild the L24. 

A bore scope isn't going to show you anything.  That collection of parts needs a lot more than new gaskets.

Okay thank you, I'll look for something else

The question you should ask yourself is do you want to rebuild an engine, or just install an engine that's ready to run.  For $400, in the states anyway, that should buy and engine ready to run.

If the engine needs new rings, or an overbore, and new pistons, you'll end up spending a lot more money and the car will be down for much longer.  You'll have a car that can't be driven and two engines taken apart, and a list of things that you need to buy.

Just for fun, ask that guy why the core plug )many people call them freeze plugs) has been removed, and why he didn't reinstall it.  Ask him if the head has been removed.

He said he hasn't done any work on it, he was going to use it as a spare engine but he didn't need it. I don't mind doing a rebuild.

Do you know a site where I could find an engine ready to run for a good price, I have been looking but nothing so far, I live in Montreal

The block and head may be perfectly fine.  If you can't find another, the question I would ask, is if he is confident everything is okay ask for a written warranty. 

The core plug looks like it was probably leaking and they threw one of the expanding gasket type HELP plugs in there.  To me $400 isn't that much IF you have some kind of proof.  Way cheaper than a rebuild and these motors are pretty stout.

The other thing you would want to do is remove the valve cover.  See if the cam lobs look clean and not rusted.  DO NOT BUY without doing this, if your even considering.  Also make sure you wiggle each rocker and check that they are in place and the rocker arm guides haven't popped out.

Thank you, if I go see the engine, what should I be looking for when I'm there?

If the guy didn't have a direct answer about the core plug I'd walk.  If it popped because the coolant froze there could be a cracked block or head.  Don't assume the best, assume the worst.  Assuming the best is the best way to lose money when you're buying used engine parts.

Edit - everything about this thread says that you're about to give a guy a lot of money for a big problem.  You're exactly the person he's been looking for, a guy who needs and engine and doesn't know anything at all about them.  He'll probably work hard to keep you hooked.

That is a very good point.  Especially being so far up north in the cold climate like he is.  In FL, I would just assume it was leaking more than a freeze condition.

Oh wait, yeah I would pass on it too.  I didn't realize the head core plug was missing too.  I was looking at the block one next to the oil filter.  That looks like the rubber expanding plug.

In your first post, you mentioned you have another 280z motor, plus the 240z motor that was seized?  Or was the 280z motor the one your thinking on buying?
