Edelbrock 416 C.I.D. 602 HP Long Block Crate Engines for GM LS 46736

This Edelbrock LS crate engine displaces 6.8 liters, or 416 cubic inches, built on an aluminum LS block and rated at 602 horsepower. A fuel-injection setup with throttle body ships on it already, along with aluminum cylinder heads, a hydraulic roller camshaft, and an internal/external balance setup suited to modern LS-swap projects.

What ships installed

Already bolted to the long block are the throttle body, intake manifold, water pump, timing cover, valve covers, and harmonic balancer, with an oil pan rounding things out underneath. The computer and wiring harness are included too, for plug-and-play EFI operation at a compression ratio of 11.2:1, firmly in high-performance, premium-fuel territory.

What is left to add

A distributor is not needed since this is a distributorless EFI setup, but a flywheel, flexplate, air cleaner, spark plugs, spark plug wires, exhaust system, and fuel pump are not included, so plan those into your swap budget. Premium 91-octane-or-higher fuel is recommended, and because no emissions certification applies to this engine, treat it as built for track days, off-road rigs, and dedicated performance builds rather than everyday street registration.

Q: Does it include the ECU and wiring harness? Yes, both ship with the engine for plug-and-play EFI operation.

Q: Is a distributor included? No, this EFI engine does not use one; ignition is handled through the included computer and wiring harness instead.
