Chevy SBC 350 1957-95 (Non EGR) LowRise+ Aluminum Intake Manifold [Polished] The dual planeThis is our top of the line medium profile LowRise+ Series manifold. It is similar to our LowRise, although slightly taller, but with several important modifications. First, it has a square bore carb flange instead of a spread bore. It also features nitrous bosses and rear water ports. This manifold will typically produce more power than any similar competitive manifold due to larger ports and runners.
