Upgrade your ride with the TSP-RESL3622LB resleeved short-block from Texas Speed & Performance, crafted for enthusiasts who demand durability and power. This fully assembled Gen 4 aluminum block features a robust 3.622" stroke crankshaft, available with either a 24x or 58x reluctor wheel, ensuring seamless integration with your engine management system.
Choose between Wiseco or CP Pistons with bore sizes ranging from 3.903" to 4.185". These 2618 forgings are designed with lowered ring lands to accommodate nitrous and boost, making them ideal for high-performance builds.
For those pushing the limits with nitrous or boost, consider upgrading to 1/2" head studs, which include ARP hardware and necessary machining. The standard setup features PRC 247cc cathedral-port cylinder heads, perfect for maintaining compatibility with cathedral-port intake manifolds. If you're opting for LS7 heads, remember they require an LS7-specific intake manifold.
For C6 Z06, Grand Sport, or ZR1 applications, a long-snout crankshaft is available, ensuring proper dry-sump oiling. Selecting this option will automatically adjust your build to include a GM LS7-specific oil pump and other necessary components.
If you're looking for a complete solution, we offer turn-key long-blocks that can be customized with your choice of oil pan, intake manifold, and throttle body. Contact us for an itemized estimate and explore the various upgrades available, including ARP bolts and Cometic head gaskets.
Your TSP engine comes with 12 quarts of break-in oil at no extra cost. Proper break-in procedures are crucial for ensuring longevity and performance, as standard oils often lack the necessary ZDDP additives.
