Interesting!  But why go Clevor?  Tim Meyer has the components to do the same thing with a Cleveland.  But wait, there's more!  My M-Block is essentially the same as that Clevor.

I guess the windsor cleavland hybrid gives the best performance. Seems to be a popular build option. The power / torque curve on that build was impressive. I can't wait to see what else they do to that 300six.

[Gary Lewis]

I disagree that it gives the best performance.  Any V8 with a 4" stroke and 3.5" bore will give the same results if using the same heads, cam, intake, carb, pistons, and exhaust.

They had to get special Cleveland heads to go on the Windsor block.  Why not just use a Cleveland block?  Drop in a 4" stroke crank and it'll be a 408 just like the Clevor, but you now don't have to use special heads.  Go with the same specs on the pistons, heads, intake, carb, and cam and you'll get the same HP and torque.

The only reason I see to build a Clevor is to use the same engine perches, accessories, etc if your vehicle already has a Windsor.  But they don't tell you that.

Clevelands have larger journals, which can limit maximum RPM...

Actually the 351 windsor and the 351M and the 400 have 3.00 main journals where the 351C uses a 2.75 main journal which is the size that the Nascar Ford engines are running. However, the 3.00 inch journal is just fine as long as the revs are kept under 6500 RPM.

And they kept the R's to something like 6000.
