Description

BluePrint Engines 383 c.i. GM Compatible Builder Series - Standard Edition - Fuel Injected - TKX Manual Transmission - Polished Pulley Kit. This engine features a true 4-inch bore, which mathematically yields 377 CID with a 3.75-inch stroke. The package ships assembled as pictured. The front accessory drive on this engine fits many vehicles, however, it is the customer's responsibility to accurately measure and confirm fitment. Note this is a low-profile design, but things such as power steering hoses, alternator wiring, and additional fittings/fabrication may be required on some vehicles. The performance aluminum cylinder heads on this engine feature a .500 raised port vs OEM.
