Things to do to truck while building 406?
I'm building the 406 to have around 450ft/lbs of torque, but I'm pulling it out of my '71 that currently has the stock 307 mated to a turbo 350 tranny. I don't know what size gears are in the rear end, but I'm worried that the 200+ ft/lbs of gained torque is going to break stuff pretty quickly. So, here are the questions:
1) Do I need to replace the stock stall to a 2500? 2) What can the stock rear and a turbo 350 stand on the torque? 3) Any other things I need to consider before dropping the engine in?
