Air hose questions
Does anyone know what the small air hose going into the throttle body and the large one below it going into the intake manifold are for on a c5 LS1?

Are you talking the small hose going to the radiator? That's the coolant hose. Some people buy a bypass kit for that. Its there for cold start issues.
The other hose into the manifold sounds like the PVC? If its what I'm thinking, that's where the catchcan goes!
