Common misconception/bad info out there, the LS1 and LS6's are 75 not 78, there was a discussion about it and someone pulled a blade out and measured it. I believe the thing is the intake opening is 78, I have not confirmed that, but have confirmed the blade size.

The inside diameter is probably 75mm which would make the outside diameter about 78mm. Hence the size of the intake.
