The modular motor was originally introduced back in 1991 in the Lincoln Town Car applications, though it wasn’t until 1996 that it replaced the venerable 5.0L (Windsor) in the Mustang, and in 1997 in the F-series
The 4.6 L (281 CID) V8 has been offered in 2-valve SOHC, 3-valve SOHC, and 4-valve DOHC versions. It has also been produced with both iron and aluminum blocks.
