Ford's 4.6L DOHC V-8 Explained - Cammer Time - Mustangs and Fords Magazine

Debuting in the '93 Lincoln Mark VIII luxury coupe, the 4. 6L DOHC Modular V-8 quickly transformed a quiet, sedate luxury coupe into a high rpm screamer with a stab of the throttle. The modular V-8 is a natural born hot rod right off the assembly line, and a powerful engine swap for your vintage Ford. The Modular V-8 has a smaller 3. 552-inch bore, down considerably from your small-block Ford's 4. 000-inch bore. When you mix the 3. 543-inch stroke (4. 6L) or 4. 165-inch stroke (5. 4L) with a 3. 552-inch bore, the Modular V-8 really is a different engine altogether. 6 Modular's small bore and nearly identical stroke (4. 6L) makes it a "square" engine where you need rpm to make power. Early on, the 4. 6L DOHC employed the Teksid F6LZ-6010-AB aluminum block according to George Reid's How To Rebuild 4. 6L/5. 4L Ford Engines book, which is available from CarTech Books. The DOHC's first aluminum Modular block weighed just 86 pounds compared with the 175-pound SOHC iron block. Teksid of Italy, a world-class aluminum casting operation, provided Ford with DOHC block castings through 2001, when Ford made the decision to bring casting work into its Windsor, Ontario foundry (Windsor Aluminum Plant or "WAP").
