Show original supplier description

The Mabbco MARINE GM Chevrolet 5.7 350 Long Block is a remanufactured engine assembly designed for standard rotation applications. This long block is specifically intended for GM Chevrolet 5.7L 350 motors manufactured between 1987 and 1995. It is identifiable by its 1-piece rear main seal, non-roller lifters, 2-bolt main configuration, and cylinder heads with center bolt valve covers. Each Mabbco long block is custom-assembled to order and includes new pistons, piston rings, rod bearings, main bearings, cam bearings, a timing set, a gasket set (including marine cylinder head gaskets), an oil pump with a 5/8" inlet, lifters, and brass freeze plugs. The engine is sold outright with no core return required. Prior to shipment, all Mabbco MARINE long blocks undergo a computerized spin test to verify proper oil pressure and compression. The push rods and rocker arms are pre-installed and pre-set. When ordering, customers must specify in the "additional information" section whether their application will use a manual or electric fuel pump. The year model of your engine may differ from your boat's model year; Mabbco Motors can assist with engine identification via phone.
