Hi I've got a question about a RS 500 inlet side, ... I know the plenum, elbow and throttle house is different, but I've been told that there is a difference in size on the inlet manifold where the injectors are placed...

I have never heard that (and I dont think it is), so does anyone in here know if it's correct that the RS 500 inlet manifold is bigger than the Sierra/Sapp and Escort inlet ???
