BluePrint BP350TBICT 260 HP TBI Core Engine

BluePrint BP350TBICT GM 350 260 HP TBI Base Long Block units deliver a high-torque sturdy engine architecture specifically engineered for TBI-equipped classic Chevy trucks and SUVs. This 5.7L 350ci build features cast-iron cylinder heads and a 9.1:1 compression ratio, optimized to provide reliable power for daily drivers or work vehicle restorations. Built with a modern hydraulic roller camshaft and a precision internal/external balance, this core is a perfect fit for iconic GM platforms like the Suburban, Tahoe, and Silverado requiring TBI compatibility.

As a precision-machined long block foundation, this assembly arrives in an un-dressed state to allow for full builder customization with existing TBI components. While the BluePrint BP350TBICT includes essential foundation items like the oil pan, valve covers, and harmonic balancer, it is protected by an industry-leading 30-Month / 50,000-mile warranty. This mechanical centerpiece is designed for builders who require professional-grade assembly standards and the reliability of a modern roller cam in a seasoned block casting protected by a one-piece rear main seal.
