Do they look the same? I just installed a 96 vortec into my 99 bravada without any issues.

The major difference is the two versions that I noticed (spent a lot of junkyard time)
was one uses an aluminum intake and the other uses a plastic.

Since you mention switching I think you have one of each. The plastic intake 4.3 has a crank sensor beside the damper pulley, and that was my main focal point when looking for a motor.

Had read of head switches and motor type (vin w and z) switches- but neither seemed as easy as using the right motor. If you have to get a new wiring harness and computer in the vehicle, it'll offset your savings quickly with time and frustration.
