Would a 429 Fit in a 1967 Falcon?

I have a 1967 Ford Falcon Futura 2-door post that was given to me by a good friend. It had a 289 in it with a 3 speed manual transmission. I found a 1969 Mercury Marauder X-100 with a 429 and C-6 transmission that I want to use in the Falcon. I have experience in building and working on cars, but no experience when it comes to working on the uni-body Fords. Will the 429 fit in the engine compartment of the Falcon? More importantly, will the uni-body design of the Falcon hold up to the torque and horsepower the 429 puts out? Do I need to add any kind of supports to the chis to make the motor swap work? The 69 Mercury Marauder is a parts car, so I have access to all of its suspension, front-end, and rear-end parts. Just need some expert advice on making this project work. Thanks!
