Into an open deck I presume. Is it possible to sleeve a closed deck block? Perhaps by removing the sleeve that's already in it and putting in a stronger one?

Yes. Blockguards stabilize the tops of the sleeves to prevent lateral motion. However (expecially in high-boost applications) they can inhibit coolant flow, allowing the tops of the sleeves to develop hot spots and possibly give out.

correct me if im wrong, but having a large bore and a less-than stroke gives you power to high RPMs right? i thought thats basically how F1 cars rev that high. short strokes and wide bores with mind-****ing CRs. is that right or am i just crazy?

I don't think bore affects the ability to rev. Actually I would think a smaller bore could rev higher. Bore is just for power. Short stroke does allow higher revs though.

Someone correct me if I'm wrong.

i believe your refering to the rod stroke ratio. long stroke engines don't rev that higgh because of the fast piston speeds at high rpm, so longer rods and shorter stroke give less piston speed and more high rpm stability. they also have less cylinder wear i hear
