BluePrint BP38318CTFD 383 Stroker Crate Engine, Deluxe Dressed

This deluxe-dressed, fuel-injected 383 runs a Holley Sniper throttle-body system in place of a carburetor, holding the same 436-horsepower, 443-pound-foot, 10.0:1-compression combination BluePrint builds through this engine family.

Installed on the engine

The Holley Sniper EFI unit sits atop a satin aluminum intake, fired by an HEI distributor. A standard-rotation, long-style water pump, a harmonic balancer, spark plugs with their wires, valve covers, an oil pan, and a timing cover are all mounted on the engine before it leaves BluePrint. Aluminum heads and a hydraulic roller cam work over the cast steel crank and hypereutectic pistons, and the engine ships with its own dyno sheet from the test run BluePrint performs on every build.

Fit notes

Like the carbureted Ready To Run 383 above, this one needs a taller hood opening than stock; BluePrint says to call ahead about special build options for Corvette applications specifically. It is not intended for use in pollution-controlled vehicles. BluePrint stands behind this build the same way it does its other dressed 383s, with coverage through 30 months or 50,000 miles, whichever a buyer reaches first.

Does the EFI system need a separate computer? The Holley Sniper unit installed here is self-contained; confirm wiring and tuning requirements against the Sniper documentation before buying supporting parts.

Is this engine new or rebuilt? New. BluePrint assembles it from new components rather than reconditioning a used core, and tests it on a dyno before shipping.
