Dyno Calibrated Brake Horsepower Torque

Operating across an RPM band of 2,000 to 6,200 RPM, this pushrod engine produces 600 brake horsepower at 5,800 RPM and 610 lb-ft torque at 4,000 RPM. A hydraulic roller camshaft features 236 degrees intake and 242 degrees exhaust duration at 0.050-inch lift, alongside 0.580-inch valve lift. Utilizing 93-octane fuel, it pulls 14 in-Hg manifold vacuum while keeping 45 to 65 PSI oil pressure.

Transmission Flange Engine Envelope Clearances

The standard Ford FE big block bellhousing pattern mates with Tremec manual boxes and Ford C6 automatics. Internal neutral balance requires zero-imbalance flywheels and harmonic balancers. The oil pan provides ample clearance over 1967-1970 Mustang steering drag links and front suspension crossmembers.

Pre-Lube Setup Prohibited Use Cases

Pressurize the internal lubrication circuit using a mechanical oil primer shaft and high-zinc petroleum fluid prior to initial startup. This engine is not built for marine wet exhaust environments, forced induction exceeding 8 PSI boost, or pure methanol fuel mixtures.

• Drain break-in petroleum fluid after the first 50 miles of run time
• Replace engine oil every 3,000 miles using specialized high-zinc formulas
• Check valvetrain lash and rocker bolt torque every 12 months
