351w is a small block and 351c is a big block.

Actually, that is incorrect. Both engines are small blocks, but from different engine families. Both use the same bore, stroke and bore spacing. But they are two, distinctly different engines where the only interchangable part is the flywheel.

They're easily identified by the valve covers, water neck and fuel pump. Windsor valve covers look just like a 302 with 6 bolts. Cleveland valve covers are much larger and have 8 bolts. Windsor water necks come out of the front of the intake, where the Cleveland has theirs coming straight up out of the timing chain extension cast into the front of the block. Fuel pump bolts are unusually vertical on the Cleveland, where on the Windsor they are the conventional, horizontal style found about everywhere else.

Find out what it's out of. It would be unusual to find a 351W with a C6. More commonly they came with FMX transmissions.

i think the old cougars and possibly mustangs sometimes came with that combination. if they came out of one of those I am definitely interested. i'm pulling a 289 out of a cougar now.

I had a friend in high school with a Cougar (I think it was a '70), 351c and fmx.

A 351w and a C6 would be common in an 80's F150 and some vans....they called it the 5.8l version at that point.

The trucks and vans have a rear sump pan....well....it has a hump in the middle and a front section that generally hangs over the front crossmember, but the deepest part is in the back. Here's a pic of the F150 version:

Thats a good deal. The 351w is a great engine. W= windsor, C= Cleveland, M=Modified, all named after where they where built. The Cleveland for a long time was thought to be better but over the years the windsor started to have a lot more parts be made for it and suddenly you could have a rather big engine that weighed a lot less making more power. In Mustangs they are used often because a lot of 302 parts work, especially the transmissions, so you could do the swap easy enough, verse needing more room, putting more weight and needing a different transmission of a 351c.

the 351 cleveland, 351 modified, and 400 are all the same engine family.
I have had 1 of each motor in the same vehicle. '78 Ford Bronco...I still miss her...
I have heard people complain about the 351M and 400, and nothing but praise on the 351 Cleveland. the only thing I ever heard about the 400 was cooling issues. But who knows what that was based on. opinions are like A-holes, everyones got one and they all stink!

Ok so the 351 Windsor, as far as the block, is alone correct?
It is different from the 289/302 because it's deck ht is taller and it's wider? right?

The 351w and mating c-6 also came in a 1977 E 150, that's what I got in my 49.

I thought it was in the same family as the 302. Least I know a lot of parts are interchangeable and its sometimes hard to tell the difference between the two.
