Intake Manifold Porting?
Basically what I was wondering is...
Can the inlet be opened up to around 80mm to accept a larger TB?
Obviously a high flow set of heads with a large cam would be prerequisite to a ported intake but once you have those, what are some typical gains of a ported LS6 style intake over an unported one?
Where does most of the material come off at... where the two ports meet? Similar to a port matching? Higher up in the runner?
