351w

When I put the 351W in my '66 Ranchero which had a 289 in it from the factory, it was pretty much a drop in. The block is taller than the 289/302 block. If that '96 V6 is a 4.3 look carefully at the motor mounts they might be the same since the 4.3 was basically a bobbed 302/5.0. Cleveland heads flow a ton. Boss 302 .. Cleveland heads. From my early in life Ford experience.
