For the last few years, there's been the big question about who really designed the 3.7L and 4.7L engines. Of course, the 4.7L came first. Way, way first. Old engineer mentor of mine told me, back when I was in high school, that the 4.7L was an AMC engine, which was put on the shelf since Chrysler already had their own V8 engine, which as we all know dates back to the '50s.
The 4.7L was originally an AMC design, which was finished by Chrysler. Years later of course since we all know Chrysler purchased AMC in 1987. The 4.7L was originally developed for the ZJ Grand Cherokee. The 4.0L was NEVER supposed to set foot (mount? lol3.gif ) inside of the ZJ at all. That was Chrysler's decision. The 4.7L debuted in 1998 for use in the WJ Grand Cherokee, and in 2001, two cylinders were deleted which created the engine we all know and love, the 3.7L V6 used in the 2002 Jeep Liberty and 2002 Dodge Ram.
Another Chrysler engineer just posted this on another forum:

(My question has always been.... how is it a Chrysler engine, when it doesn't even LOOK like a Chrysler engine?!)

Bob_Sheaves said:The 4.7 was the last "AMC/Jeep" engine (although finished after Chrysler bought them). The 5.7 was started as a formal program in 1995/1996 IIRC.
