I was just wondering what a 1969 351 Windsor motor complete is worth. It was rebuilt years ago put in a mustang probably only has 500 miles on it but been in storage since.
Thanks

You shouldn't be paying more than $1000. Does it have a carb? It would need to be torn apart, at least down to the short block just to make sure you could get away with running it. They made around 300HP stock, not bad for these light kits but I would be changing the intake(one in the pic is stock) and figuring out what cam is in it. If you change those add at least another $500.

If you want to build a high HP or stroker motor, this is the block to start with. AFAIK, the '69 is the only block made with walls thick enough to go .060" overbore.

The deck height on the 69 and probably 70 model blocks is shorter than later models.
I think it is .050". This will need to considered when buying pistons and possibly on the intake alignment on the heads.
I was building a '69 model engine and the machine shop messed it up. He replaced it with a later model. I informed him, it would need decking. He was not happy and neglected to chamfer the bore edges. More work after I got the block back.
IMO, not enough significant advantages to not consider late model engines, also.

If the intake is an original "69 4V, that is the only year it had a 4V intake for a car.
Probably some demand for restoration engines.
I do think, Ford put 4V intakes and carbs on later truck engines.
All of this is from OLD Memory, so do your own research to verify.
good luck,

Robert, something else to consider-later 351W blocks (‘94+ trucks?) were roller blocks. Some had factory roller cams, some just were roller ready blocks. These blocks had taller lifter bosses and the valley was drilled and tapped for the lifter spider + dog bones. With the older blocks, you run a flat tappet cam or very expensive retro link-bar roller lifters.
When I built my 347, I looked for a 5.0 (302) from the later years (mine was 2000 Explorer) so I can run a roller cam with factory dog bones and spider. I didn’t want to hassle with finding high ZDDP (zinc) oils for flat tappets-huge rat hole if you google :)
Food for thought.

It would have more value to someone doing a restoration who is looking for a properly date coded block than it would for any off us here.

This post is more than a year old, we can assume whatever happened, happened.
This circumstance is an opportunity to editorialize a point I made to my son about numerous Craigslist posts. Sellers claim more value stating "rebuilt, updated or modified".
Most people regard their major assemblies on OEM merit.
The rebuild process introduces an additional person's skill, wisdom and choices. How likely is that to be OEM-like? I have managed OEM car and motorcycle dealership service departments. I have had technicians that would not work on vehicle problems after an amateur had worked on them. Induced malfunctions do not conform to industry repair guidelines.
Professional rebuild/repair can be as good as OEM, documentation is reassuring, but on-line dealership reviews suggest not all dealership technicians are journeymen.
This OP may have been considering the 351W as a "500 mile" turn-key. As others commented, it may have been a "core".

Sitting for five years??? Unless it was properly set up for storage its probably nothing more than a good core now. And like JR said its long gone now.
