Product Details

The Eagle Specialty Products 13055030 Street & Strip Rotating Assembly is a complete, balanced 383 cubic inch stroker kit designed for small block Chevy 350 engines. This cost-effective performance upgrade transforms your 350 into a torque-producing 383 stroker motor, perfect for naturally-aspirated street engines running pump gas.

Complete Kit Includes:

  • 3.750-inch cast steel crankshaft for increased stroke
  • 5.700-inch I-beam connecting rods with 3/8-inch ARP 8740 bolts
  • KB hypereutectic flat-top pistons with -7cc valve reliefs, sized for 4.030-inch bore
  • Plasma-moly piston rings with standard gap
  • King SI rod and main bearings
  • Fully balanced assembly ready to install

This Street & Strip assembly is designed for engines producing under 500 horsepower and is engineered for reliable performance in street-driven and weekend performance applications. The kit features a 2-piece rear main seal configuration compatible with pre-1986 small block Chevy engines. Eagle carefully selects quality components that deliver excellent value without sacrificing durability, making this an ideal alternative to reworking original equipment parts.

Ordered some tires on Friday and got them on Monday. How much better shipping time can you get!! Best price I could find too.

Great!

Great price and fast shipping!! i would order parts again from here.. Thanks

Ordered a DiabloSport tuner for my truck here, as they had the lowest prices on the web with shipping. Order was placed on Saturday and shipped Monday. Although I received my tracking number on Tuesday, I was pleasantly surprised that they had already shipped it out. Nonetheless, my transaction was flawless. I would order from them again with no doubts.
