Inliners International Forums General Discussion Hi Performance Clifford vs Offenhauser Intake Manifolds

I ran a 4 hole 2",4" & a 2",4" open spacer.

The 2" open spacer hurt low & mid range.
Best overall performance for the street was with a 1" 4 hole phenolic spacer.

The offy has sharp turns below the four holes.
I cut out the four holes and put nice radius's into each port (3 total)
