Product Details

The Eagle Specialty Products B13057E030 is a complete balanced rotating assembly kit designed for Chevrolet 350 small block engines with 2-piece rear main seals. This Street & Strip assembly features a 3.750-inch cast steel crankshaft, 6.000-inch I-beam connecting rods with 3/8-inch ARP 8740 bolts, forged 4032 Mahle -5cc flat top pistons bored to 4.030 inches, plasma-moly file-fit rings, and King SI rod and main bearings. Designed for pre-1986 small block Chevy applications, this assembly offers affordable performance and reliability for engines making less than 500 horsepower.

Key Features:

  • Factory balanced assembly - ready to install with no additional balancing required
  • Cast steel crankshaft with 3.750-inch stroke for proven durability
  • Eagle SIR I-beam connecting rods with ARP 8740 fasteners
  • Forged 4032 Mahle pistons with -5cc flat top design
  • Premium plasma-moly file-fit piston rings
  • King SI performance bearings for rod and main journals
  • 4.030-inch bore size for .030 oversize applications

Eagle Street & Strip assemblies are recommended for use in naturally-aspirated, pump gas street engines, making this kit an excellent cost-effective alternative to reworking original equipment parts. The complete assembly provides everything needed for a reliable engine rebuild, delivering the perfect balance of performance, durability, and value for street and light performance applications.

The order was shipped promptly, and everyone was is good working condition. I will order from here again!!

good conditon! next time hopefully sooner

Fantastic price, positive communication, arrived before promised worked out great!

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,...

Pleasure to deal with, will use for future purchases as well.

I placed an order on Sunday and received my order on Wednesday morning. Product was carefully packaged and as advertised. Will buy from Autoplicity again. Thanks for the great service. Order number #18578

Very good price on k&n air filter, will definitely order from autoplicity again.

I ordered some floor mats for a Prius. Autoplicity was very competitive in their pricing. Not only that, they shipped quickly and had great feedback during and after I ordered. I would purchase from them again!
