Sheet Metal intake, their only benefit is they are built to suit your particular engine. If the cast Tunnel ram was an exact match to your combination, the sheet metal intake would show no benefit.

I don't doubt that. It's easier to add volume with spacers than to shrink it. Many SM intakes are done the same way to allow fine tuning the plenum to the specific engine.

The oldest TR were made too big on purpose - easier to install a stuffer than to add another gaskets and screws, change linkage, fuel lines, scoop position, throttle cable...
