another way to tell is pop the hood and and look at the intake manifold. LT-1 intakes are silver and the LT-4 intakes are red and the throttle body plate says " Grand Sport" And if you want to make sure its a true LT-4 Lift up rear storage door and look for the RPO code LT4 on the list.

But we all know how some people want to pass off a car as something it might not be. Even if it's a lot of trouble, someone could convert an auto to a manual 6-speed. They could alos put the red intake on.
So, if you really want to make sure look at the VIN.
8th character:
P = LT1
5 = LT4
