Edelbrock 46725 Carbureted LS 416 Victor Jr Crate Engine

This is the long block at the core of Edelbrock's Victor Jr LS 416, a 416-cubic-inch LS3-based stroker measuring a 4.065-inch bore and 4.000-inch stroke. It carries no horsepower rating of its own, since it ships with no induction system installed; the complete Victor Jr engine built on this same long block makes 602 hp and 538 lb-ft, but that figure describes the separate, fully-induced package rather than this long block alone.

What makes this long block distinct

An aluminum LS3 block carries a forged, balanced crankshaft and forged connecting rods and pistons under Victor Jr LS3 cylinder heads, part number 61339, paired with Edelbrock's Rollin' Thunder camshaft, part number 2219, and run through LS3-pattern rocker arms at a 1.7:1 ratio. Compression is set at 11.2:1, and the block carries a black powder-coated finish. Edelbrock backs this long block with a 2-year, unlimited-mileage warranty.

Before you order

Because this is a long block only, you will need to source and install your own intake, throttle body or carburetor, and ignition components to complete the swap. Its compact LS profile is built to simplify LS-swap projects into muscle cars, street rods, and trucks, but confirm your own induction and accessory drive plans before ordering, since actual output depends entirely on what you build on top of it.

Q: Does this include an intake manifold or carburetor? No, this is a long block only; induction is left to the installer.
