The Lincoln Town Car Introduced the 4.6 litre Engine to Car Lovers Everywhere
Most of us who remember 1991 think of Desert Storm, Magic Johnson’s retirement, or Bill Clinton’s announcement that he wanted to be President, but in the auto industry another first was developing that changed engine designs forever. Ford introduced its modular 4.6 liter InTech engine. It replaced the Ford Windsor V8 and the 385 V8 in grand engine fashion.

The new 4.6 liter 2-valve SOHC, 3-valve SOHC, and 4-valve SOHC Ford engines were offered in cast iron and aluminum blocks depending on the application. The bore and stroke of the 1991 4.6 liter were nearly square with a bore size of 3.552 mm and stroke size of 3.543 mm. The deck height of the block was 8.927 inches and the connecting rod length was 5.933 inches from center to center, which gave the engine a 1.67:1 rod to stroke ratio. The 4.6 litre was assembled in the Romeo Engine Plant in Romeo Michigan, and in the Essex Engine plant as well as the Windsor Engine Plant in Windsor Ontario.
The first 2-valve SOHC V8, 4.6 litre engine was installed in the Lincoln Town Car in 1991, and by 1999 the Ford Mustang was sporting a 4.6 litre 2-valve engine with upgrades like improved cylinder heads, an improved intake manifold, and a much more aggressive cam profile. This upgrade package was called the PI or the Performance improved package. By 2001 the Crown Victoria was equipped with a 4.6 litre PI package with slight engine updates. Ford had a tendency to ignore the compatibility factor so parts from one modular year to another may not fit a previous year’s engine. Parts for an engine made in Windsor may not fit an engine made in Essex.
The 4.6 litre 16 Valve Engine Became Ford’s Best Sales Friend
Ford installed the 4.6 liter 16 valve SOHC engine in all of their major Mercury and Ford models. The Grand Marquis and the Ford Crown Victoria had it from 1992 -2010. Horsepower and torque performance varied from year to year and dual exhaust was always optional. The Ford Thunderbird, Lincoln Town Car, and Mercury Cougar used it from 1994-1997, and the Mustang had it under the hood from 1996- 2004. The 3-valve 4.6 liter with variable camshaft timing was part of the redesigned 2005 Mustang.
