yea I'm pushing about 550-600 ft/lbs torque and about 600 hp. I actually just took the old TH350 and the 350 sb last night. I am rebuilding the transmission and putting in a bigger stall converter, about 2800-3000. I was thinking about going for the 3.73 gears when I do find a 9". Already have the posi trac. :secret:
