Edelbrock E11-5419 C357-B Intake Manifold sku-50025776

Edelbrock C357-B Three-Deuce intake manifold, model E11-5419, sku-50025776, UPC 085347054190, is listed in Multicolor under Edelbrock. This cast, non-EGR manifold is designed for idle to 5500 RPM with a 3x2-barrel carburetor and a balanced 180+ firing order. It has an exhaust-gas heat riser and a front oil-filler tube boss. Carburetor center-to-center spacing is 5-1/2 in.

A polished version is also listed as PN 5419. The manifold does not fit HEI; the specified carburetor is a Rochester 2GC with a small 1-7/16 in bore. It is intended for pre-pollution-controlled vehicles or engine swaps. Edelbrock says its engineers test and approve its products using equipment and test vehicles, with additional testing by professional race teams and drivers.

Its three Super Flow computerized engine dynos measure 11 engine variables at speeds up to 12,000 rpm. In 2007, it added an automated, programmable Super Flow SF902 engine dyno with WinDyn software to simulate driving conditions. Its Super Flow SF-840 eddy-current chassis dyno handles up to 1,000 hp at the wheels and 200 mph.

Edelbrock says parts enter production after meeting its performance criteria and that it is the only aftermarket intake-manifold manufacturer licensed by NASCAR.
