[quote=blykins;1491968]The 390 wouldn't have been lighter weight. All FE blocks are the same. If anything, the 427 is lighter because the bores are larger.

The 390 in question was an experimental all-aluminum FE engine. The engine would not hold up earning Ken Miles' car the nickname The Turd.
Ford wanted to showcase the FEs. However, the drivers wanted lighter cars with stroked small blocks. Ford brass won.
