Which Engine?

Which engine would put out the most torque? a 383, 378, 400, 350, or the 327? i was just wondering about this, one of myu buddys was wanting a high torque engine to go 4-wheeling with. Oh i know this will sound stupid but i for got what in the world cfm means. i got asked the other day and i said crap i forgot what i means. so i know that it sounds stupid but oh well i forgot.
