Gotta use a 6.0 block, but some folks have talked about wanting to do that. It'd basically be an old school 327. These engines rev pretty quick anyway, so unless you're building for a specific race series with a cubic engine rule, I'd probably just stick to the stock 6.0 internal dimensions. Would be cool to see though, especially if you put an L92 top end on it.
As far as the 1st question, use the 4.8 pistons on and the 5.3L crank and rods. You will have an Iron L33 Wich is the high performance 5.3L

Actually FWIW there is a very early 4.8/5.3 block that can be bored out to a 4 inch bore. The differrence is, it has a 6.0 cast above the 4.8/5.3 mark. I has been done by a few shops and is documented. Unfortunitly there very hard to find and W2W has since gone under. W2W and Lignenfelter are the only 2 Shops I know of that have done it to one of those rare blocks.
