OK, maybe this will help ....
The LS1 and LS2, at a MECHANICAL level, are VERY similar. Both are V8's. both use a single camshaft to drive the valvetrain .... both are fuel injected, electronic ignition, electronically controlled (OBD2) engines.
BUT, it is on the electronic side where they differ .....
The LS1 was first sold in 1996 .... so think about it ... the computer that controls your engine dates back to about 1994 to maybe 1995.
Are you still running any computers in your house that are 13 years old ??????
Even worse, your C5 computers use a network protocol that is kinda like "dial-up" ....REALLY slow. The C6 computers use a new network called CAN (Controller Area Network) .... but that means you can't install a C6 computer in your C5.
So .... bottom line (and interesting that it ends up being this easy) if you take an LS2 engine and change the camshaft reluctor wheel to a C5 wheel, and use a couple of harnesses provided by 3rd party vendors to connect the LS2 Throttle Body to the LS1 wiring system ... your current PCM can control the newer LS2 engine ..... this is a "doable" upgrade.
