Hello,
In response to the picture comment, i will post some of the mods needed for me to fit a 5.4 triton in a '71 bronco, but before that I would recommend trying to use a different tranny and transfer case. That is where all the major mods were found. I had to completely change my driver side frame rail to fit the tranny and transfer case, so that the body would sit down low enough. The hood will need to be modified because the motor sits 4" to 6" above the fenders. I guess the pictures will show more than i can list.
THANKS,
Brent
