4.3 vortec swap question
i have the 96-97 version ... i know that the second gens had like 3 different motors ... my question is... can i take a motor out of lets say the 98 and drop it into my 96 without having to change the ECU fuel pump and everything else ... or do i have to change all this and waste time lol

Crankshaft position sensor data is unique for each engine. Whatever engine you use, you need to use the PCM from that exact engine, or have the relearn done to the PCM. If you change from 96-97 to 98, you need to use the engine wiring harness AND the PCM from the 98 engine.
EDIT: If you use the Y pipe from the 96-97, don't connect B1S2 sensor, just leave the old one in there not connected to anything.

This is how you learn, by asking questions ECM, (electronic control module) is "old school" technology and uses a chip. A PCM, (powertrain control module) is programmed to each individual vehicle depending on how it was originally equipped: Engine, transmission, rear axle gear ratio, tire size, transfer case, etc, etc.
