Car descriptions through the years...

1970 Buick GS Stage 1 510 ft lbs .. make a Hemi worry .. Yeah, I know.... you may commence rock throwing :mad::mob: but it's no lie they were a beast. I worked at a Buick dealership on 1970 that ran a '70 Stage 2 and that thing was on another level. As I remember ( could be mistaken ) the Stage 2 heads were a dealer installed option only. Heads had to add 50+ HP and who knows what torque numbers.
