History of the 2.9L
Introduced in Late 85 on the 86 Models, the 2.9L was a larger, more powerful, fuel injected replacement for the old 2.8L Engine. It was born into the "Colonge" family of Engines which include the 2.6L Mazda, the 2.8L Ford, and the 4.0L FordMazda Engines. The 2.9 never saw duty in anything other than the Ranger and BII. Aerostars went right to the 3.0 from the 2.8 and Explorers used the 4.0 when introduced in 91. The 2.9 Co-existed alongside the 3.0, the Engine which replaced it, untill 1992, when Ford introduced a "More Refined" Ranger, the 2.9 wasnt a refined engine like the 3.0 "Vulcan". It was rough, noisy, and crude. The 3.0 was none of these things so it replaced the 2.9 in 93, even with its meager low end torque (compared to the 2.9) it still is the only Small V6 offered in the Ranger, next to the Big Brother 4.0. The 4.0 is related to the 2.9L however, so in a way it still lives on. The 3.0 is in NO WAY related to the 2.9L V6 Engine

Nothing in common other than the Ford logo. Both pretty bulletproof. The 3.0s are extremely bulletproof. Not a feasible swap in my opinion. I drove a 2.9 Bronco II for years. Intake and valve cover gaskets leak. That`s about the worst part of a 2.9.
