Hot on the heels of its last engine giveaway, Holley Performance is kicking off another engine giveaway. This time, Holley is aiming at the modern Mopar enthusiast, with a 392 cubic-inch stroker Gen-III Hemi. Assembled by Prestige Motorsports, the engine will feature a .005-inch overbore (to 3.922 inches) along with a 4.050-inch stroke forged 4340-steel crankshaft to achieve those 392 cubes.
The forged 4032 aluminum pistons from DSS Racing feature a 4cc dome and are connected to the crank via a set of 6.125-inch forged 4340-steel H-beam rods with ARP 8740 rod bolts. A custom-ground camshaft from COMP Cams is paired with a set of Mopar Hellcat hydraulic roller lifters.
The short-block is topped off with a set of Edelbrock 202cc Performer RPM Cylinder heads. The heads come complete with a 2.165-inch intake valve, 1.650-inch exhaust valve, and valvesprings designed to handle up to .680 inch of lift. A Sniper EFI fabricated sheet metal intake manifold, with an LS throttle-body pattern directs air, while a Sniper EFI 92mm throttle body acts as the gatekeeper.
A Holley Terminator-X Hemi Gen-III engine management system, along with all the required sensors from Holley EFI, control the 48 pound-per-hour injectors nestled in Holley’s Hemi fuel rail kit, along with the timing of the MSD ignition coils. Combined, the package is valued at $14,359.31.
