Which torque converter should i get???

hello everyone, this is my first post but i have been watching this forum religously for the past 6 mos. I am going to get a new torque converter for my 67 malibu but honestly know nothing about them. i currently am running a mild 350(10.5:1 comp, bored 30 over, HEI, holley 750 vacum secondaries, ported heads and intake) i have a th400 trannie with a B&M shift kit, 12 bolt rear and 4.11's. I want to have the car give one hell of a jump off the line, but now it only really chirps the tires. what converter are yall running-or do you have any good suggestions.

thanks alot,
eric
