What is inside

Displacement is 392 cubic inches from a 103.9mm bore and 94.6mm stroke, built on a cast-iron block with four-bolt powder-metal main caps and a forged-steel crankshaft. Powdered-metal, floating-pin connecting rods and hypereutectic aluminum pistons are paired with a nodular-iron camshaft, with a peak rpm rating of 6,400. The 319-aluminum HEMIspherical cylinder heads carry 54.3mm intake and 42mm exhaust valves, and compression sits at 10.9:1.

Before you plan the swap

Because this ships as a long block with no injection manifold or throttle body, budget for a complete induction, fuel, and ignition system, plus the mounts and wiring your specific chassis needs. Confirm your own state's emissions and engine-change requirements before registering a built vehicle around it. Premium fuel is recommended given the 10.9:1 compression.

Q: Does this include a throttle body or intake manifold? No, this is a long block only; both are left for the installer to source.
