Here is a little more info from Ford -
In 1992, the powertrain line was largely carried over; the E-Series was equipped with the 300 CID (4.9L) inline-six as a base engine with an option of three gasoline V8s: 302 cu in (4.9 L), 351 cu in (5.8 L), and a 460 cu in (7.5 L)). A T444E with 444 cu in (7.3 L) diesel V8 sourced from Navistar was also available, and offered with an optional turbocharger starting in 1993. In mid-year 1994, the 444 cu in (7.3 L) IDI diesel was replaced by a 444 cu in (7.3 L) Ford Powerstroke diesel, also sourced from Navistar.
For 1997, nearly the entire engine line was replaced, with only the 7.3L Powerstroke diesel remaining. A 4.2L Essex V6 replaced the 4.9L inline-6 and the 7.5L V8 was replaced by a 6.8L Triton V10. The 302 cu in (4.9 L) and 351 cu in (5.8 L) Windsor V8s were replaced by 4.6L and 5.4L Triton V8s, respectively.
During the 2003 model year, the 7.3L Powerstroke diesel was replaced by a 6.0L Powerstroke diesel, again sourced by Navistar; due to the lack of airflow in the engine compartment compared to the Ford Super Duty trucks, the version used in the E-Series required to be slightly detuned. In contrast to the 7.3L V8, the 6.0L Powerstroke is intercooled.
For 2004, the 4.2L V6 was dropped from the E150 and E250, with the 4.6L V8 becoming the base engine; for the first time in its production, the base engine for all E-Series models was a V8 (a first in American full-size vans). Output of the 6.8L Triton V10 was increased to 305 hp (227 kW; 309 PS) and 420 lb·ft (569 N·m) torque, and to 235/440 for the 6.0L diesel.
