ATK HP06M Ford 302 300 HP Stage 2 Long Block Crate Engine

Description

Power vintage pro-touring muscle cars with the ATK HP06M Ford Crate Engine 302 Stage 2 package. Engineered for classic Mustangs, Fairlanes, and Ford pickups, this 5.0-liter Windsor small-block V8 produces 300 brake horsepower at 5,300 RPM. Outfitted with an aluminum dual-plane intake, water pump, distributor, and flexplate, this long block replaces tired factory powerplants with dependable street performance.

Machinists start with a hand-picked Ford cast iron block, align-honing the main journals and squaring the block decks. A cast nodular iron crankshaft spins with external 50-ounce imbalance weighting inside a one-piece rear main seal casing. Forged steel connecting rods attach to 4.000-inch hypereutectic aluminum pistons across a 3.000-inch stroke. A 9.0:1 compression ratio pairs with cast iron cylinder heads. Sump volume holds 5.0 quarts. Dry long block weight totals 445 lbs.

Key Features of ATK HP06M

Restoration shops buy ATK HP06M crate engine units to secure proven Windsor displacement with essential front-dress hardware pre-installed. The long block drops flush into classic Ford engine bays using factory chassis frame pads.

• 4.000-inch bore iron block provides authentic Windsor architecture for vintage chassis swaps.
• OE hydraulic roller camshaft profiles produce smooth valve lift with reduced valvetrain drag.
• Cast iron cylinder heads feature hardened exhaust seats to endure modern pump gasoline.
• External 50-ounce harmonic balancer dampens crankshaft torsion across rapid acceleration pulls.
• Dual-plane aluminum intake manifold distributes fuel-air mixture to each cylinder port.
• Electronic billet distributor provides consistent spark timing across the entire powerband.
• Heavy-duty cast iron water pump circulates coolant through original radiator paths.
• Balanced ATK HP06M rotating parts isolate destructive harmonic vibrations under load.

Dynamic Windsor Dyno Output Curves

Operating across an accessible 2,000 to 5,500 RPM power band, this mid-dress Windsor long block produces 300 brake horsepower and 336 lb-ft torque on 87-octane pump gasoline. The OE hydraulic roller camshaft specifies 212 degrees duration at 0.050-inch lift with 0.475-inch valve lift. Intake manifold vacuum reads 17 in-Hg at a 750 RPM curb idle. Hot engine oil pressure runs from 45 to 65 PSI, providing continuous lubrication to rocker arms and crank journals during extended highway cruising.

Engine Bay Subframe Fitment Clearances

This Ford Windsor small block uses the classic Ford six-bolt bellhousing pattern, bolting straight to C4, AOD, and Tremec T5 transmissions. The included 50-ounce external balance flexplate mates with automatic torque converters. Factory motor mount bosses drop into stock Mustang engine bays. The front-sump oil pan clears classic Ford steering linkages and crossmembers without modification.

Break-In Protocol Maintenance Duty Limits

Pre-lube engine oil passages using high-zinc 10W-30 break-in oil before starting the starter motor. Fill and bleed the radiator to expel air pockets from the water jacket. This engine is not engineered for centrifugal superchargers exceeding 5 PSI, continuous RPM past 5,800, or raw marine sea water cooling.

• Drain the break-in motor oil after the first 50 road miles.
• Renew conventional or synthetic motor oil every 3,000 miles.
• Inspect ignition timing, distributor cap, and oil pressure every 12 months.

Warranty Coverage Pallet Crate Manifest

A 12-Month limited warranty protects against material and manufacturing defects. The banded wooden pallet crate houses the long block, intake manifold, distributor, water pump, harmonic balancer, flexplate, oil pan, valve covers, dyno verification paperwork, and startup guide. Every component arrives pre-tested and sealed against moisture.
