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.

350 should take less power to turn...but you`ll have to take into acount the gear ratio difference also.....

2.52 for the 350

2.48 for the 400

I feel the 350 would be quicker, just don't know how much and would it be worth the trouble of building another driveshaft.

It's a 10.00 index class. I don't want to use a plate, but it is on there in case I can't run the number.

play with valve lash, timing , launch rpm, chassis setup, i.e. front raise rate, front rear shock settings, you will find what you need
