On the Texas Speed dyno the engine produced 615 peak horsepower and 570 lb-ft of peak torque, and Texas Speed publishes the dyno sheet for the full power curve and test specifications.\u003c\/p\u003e\u003cp\u003eThe long block ships with the engine cradle, crate and 16 quarts of break-in oil, and the buyer chooses whether to add a carbureted or EFI completion kit. Completion kits ship separately and are installed by the customer, since ignition, fuel system and induction parts are not pre-installed on the engine. Distributor timing, fuel system setup and final tuning may be required, along with vehicle-specific fuel, cooling, exhaust and accessory components.
