Re: Pontiac's SD 455
Long stroke engines, such as the 455, are hurt much less by the loss of CR than a shorter-stroke variant.
While more compression would give more power in a racing tune, the compromises such as timing curve and valve timing are much less with the low-comp engine. And there's much less of a compromise with the torque curve because of the displacement.
