Chevy SBC 350 Vortec LowRise Aluminum Intake Manifold [Black]

The Speedmaster LowRise Manifolds are our lowest profile manifold and is also the only one that is street legal on pollution controlled vehicles. It is set up to accept a spread bore carb but comes with an adapter plate that permits the use of square bore carbs. To remain street legal with a square bore carb, you must use one that is also approved as street legal for your application.

This Speedmaster LowRise manifold is designed to fit engine swaps using the 1996 and later Vortec (Gen 1+) cast iron heads or the Edelbrock E-Tec aluminum heads. These cylinder heads are very popular in street rods, engine swaps, or the industrial market. This manifold can be used on any Chevy V-8 engine utilizing the late Vortec head.

This manifold has provision for external water bypass. It also features four corner water outlets, dual distributor holddowns, includes a square bore carb adapter and gasket, and will work with a late model style water neck, alternator, HEI and air conditioning brackets. Will also fit 1996 and later Vortec engines with some minor modifications. The modification is not to the manifold itself. It just requires running a short section of heater hose from the pipe tapped hole in the front of the manifold to the 5/8" hose nipple on passenger's side of the water pump.

The 1966 and later Vortec blocks do not have a water bypass in the block and this hose takes care of that issue.
