BluePrint Engines BP38318CT1 is a small-block Chevy long block with aluminum cylinder heads. Although the series is commonly sold under the 383 name, BluePrint specifies a 4.000-inch bore and 3.750-inch stroke, giving 377 cubic inches.
The engine has 10.0:1 compression, a hydraulic roller cam, hypereutectic pistons, a cast crankshaft, a one-piece rear main seal and external balancing at the front and rear. Included components listed by BluePrint are valve covers, oil pump, timing cover, dipstick and oil pan.
Plan the intake, fuel system, ignition and installation components separately. BluePrint's 436 hp / 443 lb-ft rating depends on the test configuration; the installed fuel system can change output. The heads have raised exhaust ports, so verify header clearance. BluePrint specifies 91+ octane fuel and no EGR application.
