What does a full groove main bearing do?

A full groove main bearing has a continuous groove around the inside diameter. This groove helps to distribute lubricating oil more evenly around the crankshaft journal, ensuring consistent lubrication and reducing the risk of oil starvation.

What is the significance of the '1974 on' note for these bearings?

This indicates that these bearings are designed for 1974 and later model year Chrysler 360 V8 engines. There may be slight design differences in earlier engines that require different bearing specifications.

Do I need to measure crankshaft journal clearance when installing these bearings?

Yes, measuring crankshaft journal clearance is a critical step during engine bearing installation. You'll need a micrometer and Plastigage or a similar tool to ensure the clearance is within the manufacturer's specifications for proper lubrication and engine longevity.

Product Details

Doing an engine rebuild on your 1974-1981 Plymouth Trailduster, Chrysler Cordoba, or Plymouth Duster with a 360 V8? Replacing the crankshaft main bearings is a critical step to ensure your engine runs smoothly and lasts. These bearings sit between the crankshaft and the engine block, supporting the rotating assembly and handling the immense forces generated during combustion.

This ACL main bearing set is built for the Chrysler 360 V8 engine, specifically for models from 1974 onwards. They feature a full groove design, which helps distribute oil evenly around the crankshaft journal for consistent lubrication. Proper oiling is key to preventing premature wear and overheating, especially in a high-performance or rebuilt engine.

When you're deep into an engine rebuild, having well-made components like these ACL bearings makes a difference. They are designed to fit right into the specified Chrysler applications, making your job smoother. Ensure you follow the manufacturer's installation instructions carefully for proper oil clearance and seating.
