Rich,
Here's a good comparison site for the LT1 vs. LT4 from the Grand Sport Registry.
http://www.grandsportregistry.com/lt1vslt4.htm
This is the very first line.
While sharing the same bore and stroke, there is a LOT more to the 1996 LT4 engine than just a red intake manifold!
So red intake manifold is your visual clue, just like Z06 Rocket says above.
Here's some info on the '96 CE. I've been contemplating one of these...or a Harley.

Hope this helps Rich.
