The Moroso Chevrolet big-block single-stage external oil pump is a tri-lobe, left-side unit rated at 1.200 pressure for external single-stage oiling systems. It’s intended for Chevrolet big-block applications that call for an externally mounted single-stage pump with that orientation and pressure rating. The pump’s tri-lobe design aligns with setups requiring that displacement profile and left-side mounting.
