BluePrint Engines B383K700 SBC 383/436HP with 700R4, Carbureted

This carbureted 383 makes 443 lb-ft of torque from a 10.0:1 compression ratio, feeding a Holley 750 CFM carburetor into BluePrint's street-tuned camshaft and aluminum heads. It ships matched to a standard 700R4 automatic rather than the 4WD-specific transfer-case version. What it is built for The higher-lift camshaft and compression here favor street driving and mid-to-upper rpm pull, the same tuning direction as BluePrint's EFI street 383 but delivered through a carburetor instead of electronic fuel injection. A dual-plane intake and polished front accessory drive finish off this long block. What to check before ordering Stall speed is 2,200-2,400 rpm on the included converter, aimed at street use rather than the 4WD transfer-case version. Confirm your application is two-wheel drive before ordering this one, since BluePrint builds a separate transfer-case-ready combo for trucks. If you are in California, confirm this engine change complies with the Bureau of Automotive Repairs policy before finishing the installation. Common questions What carburetor size does it use? A 750 CFM Holley. Is this the 4WD-ready transmission? No, this 700R4 is the standard street version without the transfer-case hardware. Does the package include a flywheel?
