I think the 4.6 was first used in 91 and has been very reliable. The 4.6 is used in Lincoln Towncars and many are used as limos. Go to e-bay and look up Towncars and sort by mileage, highest to lowest, and you will some very high miles on the engines. It's probably the most durable engine Ford has ever made. This morning, there is one listed that has 474,000 miles on it, 7 with over 300,000, 8 with over 200,000, 34 with over 150,000, etc.

The 4.2L V6 came out with the 97' models, before that it was a 4.9L I6. Same with a 4.6 and 5.4 they have also been used since 97
97+ 4.2 4.6 5.4
96- 4.9 5.0 5.8

They started the Modular motors in 91 with the 4.6, offered in SOHC in Crown Vics and DOHC in Mark VIII's. The 5.4 came out in 97, and the 6.8 in 99. There have been many revisions, mainly to the cylinder heads. The "PI" heads showed up in late 99, and 3V 4.6s in 04, and 3V 5.4s in '05.

They redesigned the 'Stang in '94 but it didn't get the 4.6 until '96. It still had the 5.0 for it's first two years.
I thought all '99 f150's had PI heads. No? How can ID mine (built 8/98)? It sure runs better than a near identical 98 I drove.
PI =performance improved
New stangs have a 3v 4.6.
