Eagle Chevy LT1350 1Pc 3.750in Crank 5.700in I-Beam Rods -18cc 4.040in Pistons Rotating Assembly

This Eagle Street & Strip rotating assembly gives you the core components to rebuild or upgrade the heart of your Chevy LT1 350 engine. Inside this package, you'll find a 3.750-inch cast crankshaft, a set of 5.700-inch 5140 I-beam connecting rods equipped with 3/8-inch ARP 8740 bolts, and forged 4032 Icon pistons with an -18cc inverted dome design, sized at 4.040 inches. It also includes plasma-moly file-fit piston rings and King rod and main bearings to get your engine turning smoothly.

This assembly is specifically put together for street applications running on pump gas and without forced induction. The 4032 forged pistons are a good choice for street performance, offering a balance of strength and lighter weight compared to 2618 forgings, and the -18cc inverted dome helps achieve a desired compression ratio with typical cylinder heads. The 5140 I-beam rods are well-suited for naturally aspirated street use, and the inclusion of ARP bolts means you're starting with strong, reliable hardware for the connecting rod assembly. The cast crankshaft is a solid choice for this type of build, balancing cost and performance for street driving.

When installing this rotating assembly, remember that the plasma-moly piston rings are file-fit, meaning you'll need to gap them to your specific cylinder bore and application for optimal performance and sealing. It's also important to note that this assembly is not CARB approved and cannot be shipped to California. Proper assembly, including meticulous bearing clearance checks and lubrication, is crucial for the longevity of your engine build.
