Product Details

Dart 31273444 Engine Block

The Big M Sportsman block was designed to be an affordable, powerful engine block. The Sportsman block is fitted with ductile iron 4-bolt main caps, and feaures a redesigned lubrication system that oils all of the main bearings before the lifters for extra reliability. We added two slotted head stud bosses on both sides of the lifter valley so you can use studs instead of hard-to-install bolts to take the place of the "missing" head bolts. Dart blocks are machined in-house on precision CNC equipment to ensure quality and to eliminate the need for expensive "blueprinting". Specifications: Standard main size, 9.800 deck height, 4.500 bore, ductile iron main caps.

  • Made start to finish in the U.S.A.
  • Works with virtually all factory standard parts.
  • Proven technology tested for the race track and for the street.
  • Cast from premium iron alloy.
  • Developed to produce maximum horsepower, strength and reliability.

fairly simple

No hassle ordering

One of the steel bars was bent on the end. I had to straighten it out with a hammer.

Website is friendly to mobile devices. Fast and confident shopping

Thanks for finding my part I inquired your company to list for my purchase, you guys are great!

Very quick easy transaction. Recommend to anyone looking for auto accessories.

great product at a great price

I hope it fits properly

This is the first time I ordered from Autoplicity. Very good experience overall. The prices are the best I can find anywhere online. It was shipped very quickly, and I received my item just in time before my trip. Thanks!

I needed two fairly expensive parts for a project. Naturally, I shopped everywhere before deciding on where to purchase them. Autoplicity had the best price on the carburetor. I continued shopping around for the alternator, and ended up right back at the Autoplicity website, because they beat everyone else on that price also! And I don't mean by a few dollars! HUGE savings! Thanks Autoplicity! In the words of Arnold, "I'll be back!"

Very poor info on shipping. Order was sent in 2 separate shipments, but tracking notice indicated everything was sent in one shipment. When I received 1/2 of my order I called & was put on hold for over 20 minutes. The world's WORST music on hold.... Good prices though.

it's a great company had the lowest price anywhere that i could find even online. great customer service that will even help you track your order all the way to your house. thanks autoplicity for helping me out and for being there with the lowest price when i needed you.
