Why not just start with a Cleveland block? If someone else is going to pay for it, get one shipped up from Australia. There are plenty there, and all the other mods would work just as well.
I am sort of confused why everybody uses the Windsor block. Back in "good old days" those were the "low performance" motors. Not that you can't make good numbers, but the Cleveland block is stronger.
