Ford Motorsports (though Genesis) is reproducing the 427 side-oiler blocks, but these blocks are "improved" in some ways, reducing the thinwall casting Ford used, and perhaps making them a little heavier, but stronger with siamesed cylinder bores. If weight is an issue, and this generally is "not" a consideration in the marine environment, then aluminum blocks are also available. I'd think anyone who was doing a full 427 rebuild, and encountered a bad block, could use two of these blocks for an essentially "new" 427, and sell the remaining good block to a collector or racer to offset the cost.
They are available up to 532 cubic inches, so if your mission on earth is to burn fossil fuels, this could be your answer!

Ford Motorsports/Genesis - Iron 427 FE Blocks
The Genesis 427 FE C5AE 65 Side Oiler Engine Project was born from a racer's mentality, to build an engine block that was one of the best and strongest ever made, based on the original Ford OEM design. Now the 2nd Gen block is on the market in both iron and aluminum, both with the proven design and high quality manufacturing expertise you expect. This block is ideal for the kit car market, the hobbyist or the full blown race market. With a wide range of bore and stroke options, it will fill practically any need. The iron block is NHRA approved for the Stock and Super Stock classes. The Genesis 427 iron block is also the current record holder in the A-Stock class.
