Here's the ultimate incarnation of FE madness. With the dual-quad intake and pent roof valve covers, the FE is perhaps the coolest looking of all the classic Ford engines. The seriously over-square engine, with its huge bore and short stroke, revs like a chainsaw; while the cross bolted main caps kept everything together at the top of the rpm range. For durability, the 427 block was the way to go, and other high-performance FE engines, such as the Thunderbird 390 and 428 Cobra Jet used two-bolt blocks. In its various forms the FE has no shortage of serious racing victories to its credit including wins at Le Mans and the 1968 NHRA Winter Nats in Pomona, California.
