I thought I saw somewhere that someone had done just that with a 390 and used 427 size sleeves to get the 4.23 bore. Can it be done? Should it be done? Can I get sleeves large enough to use a 4.310 Piston?

Dean,
You could do that, but the cost to do so would likely be much greater than just buying a new block. If you have diffuculty finding a genuine 427 block, there are lots of 390s with enough material to bore out. Just do the ole 1/8th drill bit test followed by sonic testing.
Pretty much once you get past 2-3 sleeves, it's probably time to move on unless there is something special about the block.
I still like your SPF GT
