Years ago I remember TRENDZ posting a picture of the modifications he did to a stock block. If I remember right he machined the tops of stock caps flat and then made tool steel straps that went over the top of the stock main caps. It looked super slick and if I remember right he was well over 1000 hp with a stock block.

If I end up having to redo the motor in my Fury but am too broke to buy an aftermarket block, I'll probably turn it into a 512 and use aluminum caps, not bothering with the girdle.
