BluePrint Engines B383KTKX SBC 383/436HP with TKX, Carbureted

This combo gives BluePrint's carbureted, 436-horsepower 383 a 5-speed TKX manual instead of an automatic, so the street-tuned stroker gets a clutch pedal. A 10.0:1 compression ratio yields 443 lb-ft of torque, fed by a Holley 750 CFM carburetor atop a dual-plane intake. What it is built for The camshaft and heads here match BluePrint's other street-tuned 383 builds, aimed at stronger mid-range and top-end pull rather than low-speed towing torque, but delivered through a carburetor and a manual gearbox rather than EFI or an automatic. What to check before ordering BluePrint fits a McLeod Super Street Pro single-disc clutch to this build. A hydraulic throwout bearing, bellhousing, and billet flywheel complete the package, geared with a close-ratio lower gear set for building rpm quickly. Check your tunnel, linkage, and pedal clearance for a five-speed conversion before ordering. This engine is intended for engine changes, not drop-in factory replacement, so California buyers should check their swap against the Bureau of Automotive Repairs policy.
