I'm building a 1969 f100 4x4 but I'm swapping in a 7.3 idi with a 4 speed behind it. I don't plan on towing much with it but I want to be able to get an idea of its limits ahead of time. I do tow other trucks now and then because me and my friends are always getting something new to mess around with. Will this truck handle that or should I stick with the 5.4l f350 for that
