I need to drop a tenth off of my et by next weekend. I currently have a T-400 with a steel drum in the car. I also have a spare T-350 built to handle the power. Should I throw in the 350, or will it be of no benefit? Also will the torque converter stall at a different rpm in the 350? It stalls at 6100 behind the 436 now which is about 600rpm's too high for my application.
