470 Hp 406ci
I am doing a frame on restoration over the winter and I have a friend who thinks I should drop a 406 that he builds and sells. My question is he claims the engine will bolt up exactly the same as the 350 that is in there now, however will the stock drive train handle the added 170hp or am I talking more dollars over and beyonf the engine.

You'll need a different harmonic and flywheel (or flexplate). The 400 uses the harmonic and FW to help balance the crank and are "externally balanced,..not internally balanced like your 350. Other than that, bolt it up,..good swap. 470 HP should be ok on the drivetrain with street tires.
Good luck!
