Adding to Troy's comments - an FE is an FE is an FE - it's all pretty much the same architecture. Method of oiling, side-bolted mains, don't have any bearing on an engine's personality or behavior unless you are building a motor for extremes - like turning 8000 rpms in SCCA or drag strip events - which most people won't want to live with on the street. Any motor built in the 445 - 460 size class (390/445. 428/445/460, 427/454) is going to pretty much sound the same and perform the same given the same cam, compression, intake, exhaust, carburetion, timing set up and quality of build. Their will be subtle differences based on crank stroke and piston bore between them - but you would probably need an engine dyno to distinguish them IMO.
