DART BIG M2 SPORTSMAN BLOCK BBC, 4.500″ BORE, 10.2″ DECK

Description

Achieve superior engine strength and increased displacement potential with the Dart Big M2 Sportsman Block, engineered specifically for demanding big-block Chevrolet (BBC) applications. This block addresses the critical need for a robust foundation that supports high horsepower and torque outputs without compromise.

The 4.500″ bore size allows for larger pistons, enabling greater cylinder volume and power capacity, which directly translates to improved engine output. Complementing this is the 10.2″ deck height, which provides additional clearance for longer stroke crankshafts and enhanced piston travel, expanding tuning flexibility for performance builds.

Constructed with premium materials, this engine block weighs 142.92 kg, balancing durability with manageable mass for installation. Its dimensions—56.50 cm in length, 52.10 cm in width, and 38.10 cm in height—ensure compatibility with a broad range of BBC engine components and aftermarket parts, simplifying integration into custom builds.
