Default LS swap advice

Hi Gents, looking for some advice preferably from someone who has done the same or similar install, im building a resto mod out of a 1970 Formula 400, i have purchased a 6.0 all alloy LS with a 4L80 transmission, its done 15,000 miles. I have an install kit which includes engine and transmission mounts, sump, headers, electrically im sorted with a stand alone harness, can anyone tell me will i need to cut the tunnel up for the trans to fit? what have you done driveshaft wise ? im running the stock 10 bolt diff right now, im guessing the pinion angle will be wrong and need sorting out? I have a fuel system kit that includes all the pumps, surge tank hoses clips etc etc..........if there are any other majors that ive not thought about can you let me know cheers
