It would be more correct to say that '60/61 hi-po 390s, 406s, and pre-'66 427s don't like roller cams on the street. The solid lifter only blocks have no provision for oiling the lifters except for splash feed from the rotating assembly. Street motors spend a lot of time idling and running at low RPM, meaning the lifters don't get much lubrication.
This spells death for the needle bearings in the roller lifters. The later 427 blocks and non-hipo 390 and 428 blocks do oil the lifters
but still the maintenence on a roller cam and lifters restricts their use to only the most radical street engines.
There are some good hydraulic roller cams available for the FE.
Or you could just use the tried and true mechanical flat tappet cam for the correct "sound" of a 427 Cobra.
