Engine Specifications

Every TSP-418 short-block is designed for serious performance, featuring lowered ring lands on the pistons that accommodate nitrous and boost applications. This means if you’re planning to push your engine's limits, you’re covered right out of the box.

Custom Build Options

Need something tailored to your specific needs? Texas Speed offers custom builds, allowing you to select from various connecting rods and crankshafts to perfectly match your performance goals. Plus, every engine comes with necessary oil and coolant plugs already installed for easy integration.

Optional Upgrades

For those aiming for serious power, consider upgrading to 1/2" head studs. This upgrade, which includes ARP hardware and necessary machining, is a must if you're running high levels of nitrous or boost. Just remember, you'll need to pair this with PRC aftermarket casting cylinder heads that feature larger bolt holes to accommodate the studs.

Break-In Process

Texas Speed ensures your new engine is ready to roll with 12 quarts of break-in oil included at no extra charge. This oil is crucial for proper ring sealing and engine longevity, as it contains essential ZDDP additives often missing in standard oils. After the break-in period, we recommend switching to Driven Racing oil for optimal performance.
