There are a couple of good threads here from before. Both are good motors. There is a larger selection of parts and at a slightly reduced price for the Windsor. Personally I prefer the Cleveland because of its heritage, designed purpose and its unique qualities. 350+, piece of cake, you are basically talking about a carefully built stock cleveland with a couple of speed parts. In a Cleveland, stock or hyper (I don't remember how to spell them!) flat tops < 9.5 to 1 with open chamber heads, stock 2V heads (match to pistons, quench style more efficient, given the normal prep, debur, 3 angle, etc), single groove valves, stock rockers (the tuffrided version), ford A341(A351?) cam, performer intake and 650DP carb and you will exceed your desires hp, motor will run and last for a very very long time, idle at 800 with a slightly rough idle and run on what ever gas you put in there.

Now how about 600HP?
