Basically,a butt weld is for cosmetic work( like splicing 1/4 panels) but there are exceptions,like when a seam runs the entire length of a 1/4, then it might be better to lap weld you'll get less warping... and lap welds are structural,floors and such...You'll definitely need to know both and when to use them...
That said...
cutting and welding and making a floor fit to a completely different car is a ton of extra work that will never look quite right,and fabricating a floor pan and all the braces is fairly easy and will look awesome with all new metal.
Plus you "will" want to channel or (drop the body) so I say cut out the whole floor and toss it. you can build a new one in half the time and drop the body anywhere you want it...
