Have you thought about locating a 65/66 427 FE/SO block and building up from there?
Oil management and temp are much better in the SOs than the COs/strokers and are strong running engines depending on set up. I am running mine with a moderate cam with twin quads on a high rise. good maintenance, oils changes every 1500mi (Royal Purple), etc is important also.
