The LS7 is a 7,011 cc (7.0 L; 427.8 cu in) engine, based on the Gen IV architecture. The block is changed, with sleeved cylinders in an aluminum block with a larger bore 4.125 in (104.8 mm) and longer stroke 4 in (101.6 mm) than the LS2. The small-block's 4.4 in (110 mm) bore spacing is retained, requiring pressed-in cylinder liners.

Peak output is 505 bhp (512 PS; 377 kW) @ 6300 rpm and 470 lb⋅ft (637 N⋅m) @ 4800 rpm of torque with a 7000 rpm redline.[12] During GM's reliability testing of this engine in its prototype phase, the LS7 was remarked to have been repeatedly tested to be 8000 rpm capable, although power was not recorded at that rpm level, due to the constrain
