The 265 cu in (4.3 L) was introduced in 1971 in the VH.
It used a new cylinder block with a bigger bore diameter of 3.91 in (99 mm)—the same as many of the Chrysler small-block V8s—and a new cylinder head, having slightly more hemispherical shaped combustion chambers with larger valves.

The standard version of the 265 produced 203 hp (151 kW) at 4600 rpm and 262 lb⋅ft (355 N⋅m) of torque at 2800 rpm.

The top of the line performance engine in the E49 Chargers produced 302 hp (225 kW) at 5600 rpm and 320 lb⋅ft (434 N⋅m) of torque at 4400 rpm.
The increased power is due mainly to a more aggressive camshaft, high-load valve springs, triple 45 mm (1.8 in) DCOE sidedraught Weber carburetors, tuned-length exhaust headers and a higher compression ratio of 10.0:1.

Specifications (for 2bbl carbureted variant):
Bore x Stroke Size: 3.91 in × 3.68 in (99 mm × 93 mm)
Compression ratio: 9.5:1
Power: 151 kW (202 hp) at 4600 rpm
Torque: 355 N⋅m (262 lb⋅ft) at 2800 rpm
Intake valve head diameter: 1.96 in (49.8 mm)
Exhaust: 1.6 in (40.6 mm)
