More Torque than Hp?

Hi All,
As above states what's a small block ie. 340 drive like when it's got more torque than hp. They reckon hp sells cars, but torque wins races. I love torquey motors.
I'm looking at giving my motor some performance upgrades. Key thing is I don't want a high revving hsp motor. I usually don't rev past 5000rpm. I remember reading the stories on the I think 1970 Buick GS Stage 1's with 510ft/lb torque & 375 hp. I know this was under rated & a big block motor. Is this a good thing.
you will have to manipulate a 340 with gears/ converter to react like a GS stage 1. atypicle generic GM motor with a long arm and tiny bore. I like bigger bore engines.
