89 351w
Hello.
I just bought a 89 F-250 that has a 351w from what I can tell. I still haven't seen the truck yet. But from what I can find Ford only used 351w's in 89. What I would like to know is what is different between a 351C and a 351W.

You are getting bad info. Ford used everything from the lowly 302 to the 460 in F250s.
There would be no mistaking a 351c if you saw it, but they were never offered in trucks and not beyond '75 or something either so they were all carburated. You won't find one in a late 80's F series truck.

351 "M"= Modified Windsor
The 351M from what I understand was a smogged 351C with low compression and low power output, introduced in the early 70's. As far as differences, the 351 Cleveland and Windsor use small block bellhousing pattern and the 351M uses a big block bellhousing. As far as the engines themselves, they all are built in a Vee configuration with eight pistons, connecting rods, and have a crankshaft and a cam in block with overhead valves. Joking aside, I think that the bore centerlines are the same and the bore diameters are the same. Other than that, the heads are not a direct interchange, but it's possible to put cleveland (and I suppose M heads, but who'd want to do that?) on a Windsor to make what's become known as a "clevor". What else were you thinking?

To the best of my knowledge as to what I remember, there was a difference in the bore & stroke between the two. But it's been years since I worked on those engines?
I just remember that the cleveland was manufactured in the U.S & the Windsor was manufactured in Canada, so there were differences in castings. If I remember correctly, you couldn't put a "W" crank in the "C" block, there wasn't enough clearance?

I'm not sure about the M at all, but from other people I have talked to the W has more torque than the C, and I think a longer stroke and smaller bore. I just thought I would ask here cause it seems like a lot of the members are die hard Ford fans, that would be more likely to answer my question correctly.

If I'm not mistaken, All three share a 4" bore (and evidently the same stroke to get the same displacement), but that's about where the similarities end. The 351W uses a 3" main journal diameter, while the C and M use something smaller, The 351M/400 use the same block, just a different crank to make up the additional 49 cubic inches. The cranks will not interchange between a 351W and either the 351M/400 or the 351C, but I think a 400 crank will go into a 351M/C (correct this if I've got it wrong). The heads won't swap without a lot of work, but it can be done.
