Offenhauser Dual-Port 360* Intake ~ 'Was It A Gimmick'
~ Offenhauser Dual-Port 360* ~
Tricks from Offenhauser
A} Have the Primary Jets in the Carburetor on the 'lean side'.
B} When the Secondaries open up, the 'high-velocity' of the smaller Primary
Runners will bring the Secondary-flow along for the ride.
C} A Mid-Range Power {2200 to 5500 RPM} Camshaft works best with this
'Dual-Port' Intake.
