John, the simple answer here is No. The 390 and 428 blocks are different even though they may have the same or similar casting #s. There must be 200 variants so there's no need to go into them here, but the books that you ordered will shead some light on the subject as well. I went through this vertical learning curve just a while ago as I started sourcing parts for the 428/462 that I'm building for BDR687.
