Sky, supposedly, you ca gain 30-40 HP with a good short block. We're talking a blue printed short block with a torque plate bore honing, and perfect squaring of the crank to the bores and deck.
Gapless rings and a perfect head fitting (valve stem seals, etc.) are su8pposed to mean a lot too.
Most times, all this is only done on competition cars, but it does count, according to the experts.
