Have you been wanting to experience the potency of a Gen III Hemi with some guts in your project car? Like the idea of hairy Hemi power but want to stay naturally aspirated? Want to know what 600 horsepower of modern Mopar grunt feels like in your project car? Then enter today to win Holley's 2023 Hemi Engine Sweepstakes today for your chance to win a 392 cubic inch stroker build from Prestige Motorsports!
Starting with a basic 5.7L Hemi like you'd find in just about any modern Mopar, Prestige Motorsports got to work on beefing up the already solid powertrain. Bored and stroked to 392 cubic inches (or 6.4 liters of displacement, if you prefer), the heavy moving parts consist of a 4340 forged steel crank, 4340 steel H-beam connecting rods with ARP bolts and forged pistons that have been balanced and blueprinted. Paired off with a set of aftermarket CNC'd 69cc heads, a Melling high-performance oil pump, a custom-grind camshaft, a billet steel double-roller timing set, Hellcat hydraulic roller lifters and guides, and Fel-Pro gaskets, this 392ci unit has the bones to be something great.
And that's where Holley comes in. Our Center-Sump oil pan and dipstick tube will keep the lifeblood of the engine right where it belongs, while up top a Hi-Ram EFI intake manifold, fitted with a 105mm throttle body and 120 lb/hour fuel injectors will properly feed this beast. A Holley EFI Terminator X management system will keep everything in check, while MSD ignition coils fire off the mixture. A Holley Mid-Mount Accessory Drive Kit with an SFI-certified front damper cleans up the front dress, and to top everything off are a set of Holley Sniper fabricated aluminum valve covers. The end result is an engine that will crank out over 600 horsepower naturally-aspirated. Yes, we know Hellcats pump out bigger numbers, but they require a blower the size of a cinder block to turn out 700+ horsepower! Set this mill into a 1971 Dodge Demon and you'll be able to go toe-to-toe with a Challenger SRT Demon! Add some howl to your 'Cuda, Charger, D-series truck, B-series van...whatever you can fit it into!
