Ok, so one engine plant is located in Canada and the other Ohio. What else is different?
The 351 Windsor (biggest displacement of the Windsor family – which included the 289 and 302) had a beefier block than the Cleveland, which in theory allowed for more abuse and longer life-span.
The Windsor also came first in the history being used from 1969 to 1998.
The Cleveland was used from 1970 to 1974 (much, much shorter run), with 1971 bringing 351 C Cobra Jet.
Unlike the Windsor the Cleveland had canted multi-grooved valves. It also required larger rounded intake and exhaust ports.
There is another major difference and that was how the engined were cooled. No we aren’t talking water vs. air (these weren’t VW engines) we are talking about water flow.
Like the 289 and 302 the 351W used a front cover and water existed the intake manifold face of the cylinder head through intake manifold to the radiator. The 351C don’t have the front cover. The block is extended and the covered with a flat stamping. Water existed the combustion face of the head and into the block and then to the radiator. This is important to note, particularly for me. Why:
The Cleveland and Windsor heads are interchangeable only with modifications to the water passage. I currently have a set of 351C Cobra Jet heads to put on my Windsor family 302. I’ll have to have those mods done when I have the heads rebuilt.
Not the same location as the 302 Windsor.
There you have the basic differences between the Cleveland and Windsor families.
Thanks for reading.
