Product Details

The ATK High Performance Engines DM02 is a complete remanufactured marine crate engine designed for 1964-1980 Chevrolet marine applications. This 5.7L (350 cubic inch) small block Chevy delivers reliable 270 horsepower performance with proven marine-specific features.

Engine Specifications:

  • Displacement: 5.7L / 350 cubic inches
  • Power Output: 270 horsepower
  • Compression Ratio: 9.0:1
  • Block Type: Cast iron block with cast iron cylinder heads
  • Balancing: Internally balanced for smooth operation
  • Rotation: Standard rotation

Marine-Specific Features:

  • Port side dipstick configuration for marine engine bay access
  • 2-piece rear main seal design (pre-1986 style)
  • Flat tappet camshaft for reliable marine performance
  • Built to handle marine environment demands

This engine is engineered specifically for marine applications, replacing original 350 small block Chevy marine engines from the 1960s and 1970s. The 9:1 compression ratio is optimized for marine fuel requirements, while the cast construction provides durability in harsh saltwater and freshwater environments. As a complete long block, this engine includes the block, heads, camshaft, and internal components—ready for installation with your existing marine accessories.

<br><br>Borgeson 000940<br><br>I found Autoplicity during a price search on the Borgeson steering shaft for my truck. I had never heard of them, and was a bit skepticle. But after doing some research, found that Autoplicity has a good reputation on a Jeep forum I visit.<br><br>I decided to order, and I am impresed. Extremely fast shipping, I placed my order on Saturday, and its now Monday before noon. I am holding the new part!

Dont kno just ordered

Order process was fast

Fast checkout

Fast and easy!! Thanks!! aaa++++

Extremely FAST shipping. Ordered K&N air intake on Tuesday evening and item was delivered Thursday morning!! Item as advertised. The package got here before UPS could upsate the tracking number!! Great service!!

Good price.

Prices are great on this site. The layout and checkout process are easy to use; Google checkout is definitely a plus. Shipping could be a little faster, especially if they had drop ships from their supplies for items not currently in stock. Overall good service and no problems.

glad to find this web

This is the first time I've ordered from this site, but things look good from what I can tell so far. They had the parts I was looking for (including a fairly specialized racing part) for a price slightly lower than other places I had looked, and my order shipped the next business day. At the time I wrote this, they were also offering $5 back on my order for writing a review. ;-)

Great company. Had part in stock ready to ship

Bought a sparco steering wheel. Best price on the net. And shipping was very fast. Thank you

I was surprise to the how fast the order was shipped and the item is just like describe and the lowest price on the internet. I am very satisfy.<br><br>R<br>Brooklyn, NY
