Description

Cut quarter-mile sprint times using the ATK HP19C Ford Crate Engine 502 Big Block Complete package. Engineered for classic Ford muscle cars, street rods, and drag machines, this 8.2-liter 385-series V8 produces 525 brake horsepower at 5,400 RPM. Complete with aluminum cylinder heads, four-barrel carburetor, intake, distributor, water pump, and ignition hardware, this turnkey package produces immediate big-block performance.

Engine machinists hand-select seasoned Ford 460 cast iron blocks, precision align-honing main journals before clearance-notching the block for stroker rods. A nodular iron stroker crankshaft spins with internal neutral balance weighting inside a two-piece rear main seal. Forged steel connecting rods attach to 4.390-inch hypereutectic pistons across a 4.140-inch stroke. A 9.5:1 compression ratio pairs with high-flow aluminum cylinder heads. Oil sump capacity holds 6.0 quarts. Dry turnkey weight totals 565 lbs.

Key Features of ATK HP19C

Car builders buy ATK HP19C crate engine turnkey packages to install colossal 502 cubic inch displacement without hunting for compatible induction or ignition equipment. The turnkey long block drops flush into vintage Ford engine bays using stock 460 frame perches.

• 4.140-inch stroke crankshaft expands displacement to 502 cubic inches for massive pulling torque.
• High-flow aluminum cylinder heads optimize high-volume airflow while shedding front-end engine mass.
• Performance four-barrel carburetor meters fuel uniform across rapid acceleration demands.
• Dual-plane aluminum intake manifold optimizes air-fuel mixture distribution across all cylinders.
• Hydraulic flat tappet camshaft profile produces wide mid-range torque and classic big-block idle tone.
• Billet electronic distributor and plug wires generate strong ignition fire across all cylinders.
• Cast iron water pump circulates coolant through factory cooling systems without modification.
• Balanced ATK HP19C rotating components isolate destructive vibration under full-throttle track loads.

Dynamic Big Block Dyno Output

Operating across an authoritative 2,000 to 5,500 RPM power band, this turnkey 502 big block generates 525 brake horsepower and 560 lb-ft torque on 91-octane pump gasoline. The hydraulic flat tappet camshaft specifies 224 degrees intake duration at 0.050-inch lift with 0.530-inch valve lift. Manifold vacuum measures 16 in-Hg at a 750 RPM curb idle. Hot engine oil pressure runs between 45 to 65 PSI, keeping large-diameter main journals and valvetrain parts lubricated with pressurized oil during extended acceleration pulls.

Engine Bay Subframe Fitment Clearances

This Ford 385-series big block utilizes the classic 429/460 bellhousing pattern, bolting straight to C6, E4OD, and Tremec manual transmissions. The included internal neutral balance flexplate accommodates automatic torque converters. Motor mount bosses align with factory 460 chassis frame perches. The front-sump oil pan clears steering linkages and suspension crossmembers without cutting.

Break-In Protocol Flat Tappet Limits

Pre-lube engine oil passages with high-zinc mineral break-in oil using a mechanical primer before starter engagement. Run the engine between 2,000 and 2,500 RPM for 25 continuous minutes to seat flat tappet lifters. This engine package is not engineered for supercharger boost exceeding 5 PSI, continuous RPM past 5,800, or raw marine sea water cooling.

• Drain high-zinc break-in motor oil after the first 50 road miles.
• Renew high-zinc or synthetic motor oil every 3,000 miles.
• Inspect valvetrain lash, distributor timing, and spark plugs every 12 months.
