offenhauser 4bbl 360 intake??

The thinking was a 2 intake manifolds in 1 set up. Both single plane. The primary is a narrow port, single plane with a high veloity idea behind it. The secondary side is the same idea just seprated completely. When the secondary side of the carb kicks in, the idea is the intake operates as a single plane intake.

It is an attempt to create a intake with a higher RPM spread and performance band. The small narrow primary side, even though a single plane should provide enuff low end, high velocity air speed to act well down low while the secondary side completes the rest and extends the RPM band as a single plane would.

The RPM takes this intake to the museum.
