Chevy 454 Long Block Crate Engine
$1,895.00 – $2,495.00
Our Chevy 454 Long Block Engine is on sale. This 7.4-liter engine is known as the “454 Big Block.” In 1970, the 454 was first introduced for use in the Chevy Corvette; soon after, its use extended to a long list of GM and Chevy applications. 454 motors have withstood the test of time, have been in production for four decades, and ended in the early 2000s with their Generation 5 model. Our company has been remanufacturing this engine since its conception. Throughout the years we have developed a state-of-the-art process and upgrades that increase the longevity of every 454 long block that we build. Unlike most rebuilt 454 engines, our parts, testing, and build process give our customers unparalleled confidence in our product.

- 70-90 Car/Lt. Truck – 2 Pc. Rear Seal: No Price Change

Description
OEM REPLACEMENT Our precision remanufactured 454 block
Every Chevy 454 block must pass our magnaflux inspection designed to detect any microscopic flaws or cracking. Blocks are then thermally cleaned, followed by steel microblasting until they achieve a brilliant appearance. Once a block is fully cleaned, we begin our precision boring and honing process. Using a carbon two-stage power hone, we can maximize the sealed area and ensure that it precisely meets the recommended RMA readings. Computerized micrometers are used to resize rods in strict accordance with factory recommendations. Crankshafts are precision cut and micro-polished to achieve a 12 RMA reading or better.
Custom 454 long block assembly
We meticulously mill each cylinder head until perfect alignment and sealing of the head gasket is achieved. Our cylinder heads are assembled using a new valve stem and seals that feature high-temperature technologies, increasing heat resistance and longevity. These polished cylinder heads are pressure tested using magnetic detection to eliminate the chance of cracks or flaws unseen by the human eye. Before each head is mated to their block using the correct torque valve, we vacuum test all seals for proper seating. Triple-angled cutters are used to machine the valve seats, ensuring proper pressure and flow. All valves, valve springs, and valve guides must pass our stringent process of meeting and exceeding OEM specifications. O.H.C. heads are aligned for proper bore consistency. Every remanufactured long block has been specifically engineered to help improve the inherent flaws and failure points that can be found in many of today's engines.
