When it comes to Small-Block power, GM Performance’s keep finding new ways to add muscle to the iconic American V-8. They’ve developed new Fast Burn cylinder head castings that incorporate beehive-style valve springs and complementing valvetrain components. The result is greater high- rpm range and durability – and power. The heads are the stars of an all-new GM 6.5/6.2 crate engine and an  updated version of the big-torque GM 6.2L - 6.5L stroker engine. The 6.2L is rated at an impressive 400 horsepower, which is more than any small block 350 offered in a production car. The GM 6.5L is rated at 450 horsepower. Both engines complement those high-rpm horses with low-rpm torque – at least 300 lb.-ft. by only 1,500 rpm – for that unmistakable feeling of immediate power that comes only from the Small-Block.
