Description
Offer: BluePrint Engines BP38350CT1 383-stroker long-block. This is an engine assembly, not a complete engine installation package.
Application and fitment
BluePrint specifies this engine for 1996–2000 Chevrolet pickups or SUVs originally equipped with a 350ci (5.7L) engine. Factory fuel injection is required for the manufacturer’s stated emissions-compliance application. BluePrint says no ECU tuning or recalibration is required for that application. Confirm your vehicle’s year, original engine, fuel-injection system and emissions configuration before ordering; the stated application is not a universal fitment guarantee.
BluePrint describes the engine as 49-state legal under CARB Executive Order D-824-1 for the specified application. Check the order and emissions requirements that apply to your vehicle and location.

Installation checks
If retaining the OEM front accessory drive, existing mounting brackets may require modification.
