Windsor Verse a Clevland
 

Ok I have a Heavily Modified 351W In My 91 Lx But Ive never Understood the Lore about the 351C. The windsor Verse the Clevland Engine To Me its Like say I have a 4 speed Munci. To me that means You 4 speed manual Transmision was Built at the Munci Indiana Plant. The 351 Clevland was Made In Clevland Ohio the Windsor,,, To me this is all just Plant designation so what am I not getting?

The C and W are 2 completely different engine designs that only really share displacement,motor mounts and bellhousing patterns. Everything else is different. The C was basically an all out racing design (originally); a "small block" engine with "big block" heads on it. In reallity the C isn't one or the other (small or big block).

The only reason for the letters is because Ford made 3 unique 351 displacement engines within a short time period that needed to be identified in different ways. The 351W (just a tall deck 302 with a longer stroke), the 351C (high performance mid sized engine of the early '70s) and the 351M (destroked 400 to fill in for the high demand for 351 engines after the C was discontinued and the Windsor plant couldn't keep up with the demand).

So you see, it's not just plant designation, but engine identification.

By the way, the 351M was cast at both the Cleveland Foundry (CF) and the Michigan Casting Center (MCC), so plant designation falls apart there.

Hope this helps.

I can see clearly :p
 

Yes Thank you.

As previously said there are some big differences between the 351W and the 351C. One of the biggest thing about the clevelands were the heads. They used heads with a canted valve kinda like the chev 350 uses. They are said to be one of the more powerful small block heads that ford made. The block also boasts many differences in that the water jackets are different and the blocks are usually 4 bolt main blocks. Some of the clevelands actually took parts from the boss mustang. I know the cleveland in my dads car was built using the Boss crank and its supposed to be good to like 8000. They are very well built engines and great for modding the only disadvantage is finding a good one and the aftermarket parts arent as readily available.

The 351C has smaller main journals which accept higher revs a little easier also.

Keep in mind as well that the 302 was actually made at the Cleveland plant, not the Windsor plant. The 302 shares design similarities with the 351W, which is why it is often called a Windsor engine, but in reality, it's not.

Take care,

This Is a Bit of a step to the right
 

But Follow Me Here Ok from what Ive learned about "What is a Stroker engine" and about the 351 It seems Litterially that the 351 is Nothing But a Factory Stroker. Or Im I completly worng again :p

no the 351 has a higher deck casting height
than a 302
you can strock a 351 to 454 in theory if you had all the right parts
stroking a 302 to 351 is quit a hard task thats why 347 are about the max.
302 and 351 w arent the same blocks intake manifolds wont interchange and most offten you need difrent headers.
dont think about it as stroking but adding cylender bore up higher on a 302. a 351c is better stock but parts are pricy and hard to find.

in a pinch you can bolt 351c heads on to a 351 w but you have to make your own intake manifold since b&a stopped making theres

ive been told a 347 is actually 350 cubes but ford didnt want to advertise it as a 350 because of the 350 chevy. I dont know if it has any truth behind it though. Guess u would have to do the math.

A 302 block bored out .030 over and stroked to 3.400 is 347, not 350. ~Brian
