And while vintage 409 manifolds had road draft tubes, Edelbrock's Chad Magana cleverly hid a PCV valve at the rear of the intake manifold for more effective crankcase vapor and pressure evacuation.

However, the brilliant minds at Edelbrock knew that using the knowledge and experience they've achieved through decades of intake manifold development could improve upon GM's 15-year-old design.

While most Honda nuts always go for broke with a DOHC engine there are the few that either don't have the money to swap out to a twin cam power plant or just simply choose to make the most of what ...

Unless you want to invest in a custom made-to-order sheetmetal intake manifold, there's no way to run three two-barrel carbs (or TBI analogues) with factory high-perf 409 or Edelbrock cylinder-heads.
