Keep on Boating with a New ATK Marine Chevy Crate Engine

Is your boat stuck dockside with a broken motor? Give that old lump the heave-ho and drop in a freshly remanufactured ATK Chevy 350 or 4.3L V6 Long Block Crate Engine. All blocks are magnafluxed, bored, and precision honed, and the main journals are line-honed. Crankshafts are stress-relieved, precision ground, and micro-polished. Cylinder heads are magnafluxed and machined for three-angle valve seats, then fitted with new intake and exhaust valves.

ATK Marine Crate Engines are packed stem-to-stern with high-quality parts for maximum performance and long-term durability:
• Marine-spec pistons and rings
• Marine-spec hydraulic roller or flat tappet camshaft depending on application
• Marine-grade gaskets, seals, and freeze plugs
• New main, rod, and cam bearings
• New lifters, rocker nuts, and swivels
• Heavy-duty double roller timing chain with steel cam sprocket and crank gear
• High-volume oil pump

ATK tests each engine for compression, oil pressure, oil leaks, engine noise and general operating conditions before shipment. They also back the engines with an 18-month limited warranty.
