BluePrint Engines B383FK700 SBC 383/436HP with 700R4, EFI

This BluePrint 383 combo is the street-tuned, fuel-injected version, running 443 lb-ft of torque on a 10.0:1 compression ratio by way of a Holley Sniper 2 EFI system. It comes matched to a 700R4 automatic transmission rather than the 4WD-specific version, with a polished front accessory drive already installed. What it is built for The camshaft, aluminum heads, and EFI tuning here favor stronger mid-range and top-end pull for street driving rather than low-speed towing, which separates it from BluePrint's 4WD truck version of the same displacement. A dual-plane intake, Pro Series ready-run distributor, and complete EFI fuel pump kit are built into the long block. What to check before ordering The converter here is set up for a 2,200-2,400 rpm stall, built for street driving rather than the transfer-case-ready hardware found on BluePrint's 4WD 383 combo, so confirm this is the right version for a two-wheel-drive application. Because this is an engine-change component and not a stock replacement, buyers in California need to follow the Bureau of Automotive Repairs rules covering engine swaps. Common questions Is this the same camshaft as the 4WD version? No; this street combo uses a higher-lift, longer-duration cam suited to on-road driving. Do I need a separate flywheel? No, automatic transmissions run on the flexplate already included with this combo. What finish is the accessory drive? Polished, matching the rest of the front-end hardware on this kit.
