Identify engine? 351c, w, or m?

I recently bought an '83 f250 for 1g, rusty as heck but solid frame, supercab, sorry getting off the subject...

How do I tell if my 5.8 motor is a windsor, cleveland, or modified? Can I tell by the VIN?


sorry... Which one do I *want* to be in there? I'm more interested in reliability than performance.


Thanks in advance...

Hey Lectric and welcome to FTE!

I can tell you for sure that it's not a Cleveland. Not stock anyway. Ford quit making Clevelands in 1974.

It could possibly be a 351M. Although I believe Ford quit putting them in trucks in '82. Not sure about that though.

I have an '83, and according to my owners manual the only engines available were the 300 six, the 302(what mine had), and the 351W (which is what I put in it)

The 351w will give you many years of trouble free service as Ford continued using them until---?

To be sure though, and to answer your question, look at the fuel pump. Two bolts verical from each other -351M, two bolts horizontal from each other -351w

And just to make sure it's not a 302, look at where the timing cover, block, and head come together. If there is an inch of space between the head and the cover, it's a 351. If the head sits right "on top of" the timing cover, it's a 302.

Franklin2 I believe has a neat diagram illustrating this.

Hope this helps!

Again, welcome!

Chuck

vertical from each other? You mean just plain vertical or horizontal, like either screwed into the block up and down in relation to the ground or sideways?

Thanks again!

Sorry 'bout that Lectrick. I guess I could have made myself more clear.

Regarding the fuel pump:

If it has an upper bolt and a lower bolt it's an M.

If it has a front bolt and a rear bolt it's a W.

If it has a cast timing cover, it's a W.

M-block engines have a flat, stamped plate that covers the T-chain and sprockets.The timing assy. sits recessed into the block itself.

And lastly, and perhaps easiest, Windsor block engines have 6 bolts per valve cover. M-block engines have 8.

For some background on each of Ford's engines, Steve's link is excellent.

351m has 8 bolts on the valve cover.

351w has 6 bolts on the valve cover.

it's a windsor and the guy I bought it from says it was rebuilt about 70k ago. It sure acts like it, it's got very strong oil pressure, is pretty snappy and all the fluids look good, no knocks/lifter/rocker noise.

Thanks for all your help in indentifying characteristics. I really like this forum, I should be around for a while.
