Yeah, those GM 305s and the 350s were torque monsters. Depending on the year and size, plus if you stroked it out to like a 383 or something like that; 400 ft. lbs. of torque would be nothing for that engine. My 87 had 325 ft. lbs. and it was almost stock.

My buddy has a built 98 Camaro, supercharged LS1 with all sorts of other crazy stuff done to it. He just got it dyno'ed: 535 rwhp 580 ft. lbs. of torque running on 8 lbs, no juice. Blows my mind...
