LT1 Intake Manifold Question
How hot should the intake manifold of a 97 Camaro Z/28 be? My Camaro intake gets hot enough to be hot to the touch, and you can't hold your hand on it for more than few seconds. The reason I ask is because I know that the LS1 has a nylon/plastic type intake cover and it only gets slightly warm, but I don't know how hot the LT1 should be even though it's metal.

You really shouldn't be concerned with putting your hand on a hot engine. The LT1 is designed to run well past 200 degrees. Since it has a metal intake, it's gonna be hot.

Two things to consider, if it's "really hot"......
- is the heat shield still on the bottom of the intake manifold? There's a sheet metal cover that keeps hot oil off the bottom of the manifold.
- have you done the throttle body coolant bypass? Removes the hot coolant from the throttle body, minimizing heat transfer to the intake manifold from the coolant. Picks up free 6 HP at the same time.
