For reason to numerous to go into, my 97 Camaro SS has been sitting for several years without an engine. Several weeks ago I purchased a used LT1. I got the motor installed and have it running. When I tried to install the SS airbox I ran into a problem with the driver's side AIR check valve. The valve sits too high and I cant get the airbox in place. The motor is out of a 96 Camaro or Firebird. Were there different types of valves? It seems like the pipe that comes out of the manifold is too tall. Can I cut the pipe shorter so the valve sits lower? I don't really remember what the one on my original LT1 looked like. Not really sure what to do here.
