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

I agree. If you do want to use the block,I'd have all of them sleeved. As a machinist, we would suggest that to individuals that were wanting to do Hp work.The steel sleeves usually used are stronger than the cast iron ones that they are cast with and doing all 8 makes the block stronger, as well making the cylinders more uniform in heat transferal.
So as posted, unless you have "need" for that particular block....I'd get a new aftermarket block. Just the fact that a center oiler is already 40+ years old( and 427s weren't typically grocery getters), I would venture that some of the other metal might not be up the the power that some new sleeves might take.
