True.
" The SOHC 427 represents the ultimate development of the FE engine. By eliminating the rpm barrier of pushrods and lifters, the engine could run easily at 8100rpm and hit 9000rpm for short periods. The hp curve was practically a straight line up to 7000rpm, and in an 8V version reached 700hp. A dual overhead cam version was planned, but never developed, as NASCAR once again squelched this ultra high performance gem from Ford."
