Product Details

Dart 31273454 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, 10.200 deck height, 4.500 bore, ductile iron main caps. -10.200 decks allow for increased displacement and longer rods for a better rod ratio.

  • 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.

Wonderful

Fast delivery and great price

Everything was good but it's not the exact part needed

Great

Everything was as expected

Dear It was a good product that I was looking for, thank you so much Regards

Received product fast was exactly what I needed thanks

I had a great experience shopping at autoplicity

Great price found for my product. excellent customer service and my item was in stock.

Ordering was very easy and product was delivered within a week. I ordered a battery and it was received in good condition and works. I would recommend autoplicity to others.

This is our second order from Autoplicity. The first one didn't go so well due to a mix up with the Sparco seat pricing. Though I was starting to question our decision to order from them after several emails and phone calls and online chats, they came through in the end. These guys earned our second order by honoring the price they had listed and then calling to follow up when our race seat was shipped. Since this group was able turn our bad experience into a positive one we made our second order and, so far, it looks like they are again getting us what we want at the best price we can find. We are happy to recommend Autoplicty and plan on using them for future orders. There is one specific thing we would recommend, change the quality and volume of the hold music on the 800 #. It sounded like we were calling a 1970's van with a blown Jensen stereo turned all the way up,...

Shipped very quickly and had the best price I could find!

Great prices on most things. Ordered on a sunday and they processed and shipped the order the next day.

Easy to order

first order fast shipping and great fit

So far, extremely easy to Submit orders

This was my first order with Autoplicity and I am very happy. They had the lowest price on-line that I found. Communication was great and shipping was very fast. I ordered late on Thursday and it was at my house the following Tuesday, and I didn't pay for rush shipping. I got exactly what I expected. Will do business with these guys again.
