which one th-350 or th-400?
When ordering your converter be sure to mention the fact you are going to be on the juice nad they will compensate. I think a 3600 would work and on the juice you should go into the low 4's. It will keep your NA stall good and on the juice you'll be in your torque curve and very close to your hp curve.
