340 vs. 440? (Help)

...and i like em both. Hell of a tough small block ....BUT....there is definately a difference. Driveability i'd go with the small block ....BUT ..... getting your heart rate up like the doctor suggest for us older farts... go the Big Block. The Big Block drives like a champ and don't do that bad on gas but the population gets all google eyed when they see that Big Block run. It's a street machine and even the wife request that i take her to the E.R. for treatment of whip lash when i put it to the floor from a signal. I guess i need to start telling her when i'm going to do that.
