If you had the plugs out when you tried to turn the engine, you are likely correct.

Any RN B5234Tx would drop right in and run. Just use the 94 850 accessories. Swap out any VVT with the 94 Cam sprockets.

Still, it should move, even with the plugs in. It'll just be more difficult. (Unless it *is* seized)

Ok...I got this bad feeling that's what's going on, there's still hope isn't there???? I'm going to try with the plugs out. Now you guys do realize I'm a woman right ( : I've done so much wrenching in my life,my Grandpal gave me that gift. Some things I have to have that physical strength, but whatever it is I that's an underlined I get it done! No offense.i love wrenching and my 850 is my baby.

OP do you know if your car has VVIS? Also I'm assuming this is a non-turbo car but didn't see that in the post?

Most (all?) 94 850s are plagued with VVIS intake which means the manifold ports are a different shape and won't match the ports on an RN head. So if you want an RN engine you can't keep the existing intake manifold which means you can't keep VVIS or for that matter the EGR (I think all 94s also have EGR), all of which would make the ECU unhappy.

So using an RN engine gets tricky here, seems you would also need the right intake manifold? Or perhaps a head swap but that is beyond practical. There are 95 850 intake manifolds with EGR but all VVIS manifolds have the square ports. Maybe you can adjust something to just run without the VVIS, there are some good posts about VVIS in the archives here if someone wants to search and read

. Then you only have EGR to deal with.

Searched the OP posting. He has a 1994 Volvo 850 wagon non-turbo wagon.
That would be one of these:
1. B5252FS ( 10 valve ) with Siemens Fenix 5.2 no V-VIS
2. B5254FS ( 20 valve ) with Bosch LH-3.2/EZ-129K and V-VIS.

If he just wants to fix it and cannot find a N engine. NA RN lower end with the N Head ?

Yeah as I mentioned, could swap the head too but that's getting overly complicated IMO.
