Intake Manifolds
Offenhauser never made a dual Pane intake manifold. Their low-profile manifolds are a split plenum single plane. Not the single plane design like a Victor or Torker either. 50s tech. They made a "Dual Port" which does not accomplish the claims Offy made. Offys Tunnel Rams and Port O sonic single planes are good within their category- stock hi po iron heads. IMO Offy intakes are better to hang on wall for conversation. Id run a performer on a 318 before Id run a single carb Offy intake. And the performers intake ports are sized for the 340/360- even so Id run one on a 318. Now if you want to run dual quads on a 318- Offys unit is more readily available than the Edelbrock D66. I resealed the intake manifold on my 1995 318 Dakota. With the Keg removed I placed my Offy 2x4 for 273/318 on my 318 Mag just for the heck of it. Looks cool.
