Big block swapping a 1964 barracuda

I have a 1964 Plymouth barracuda and I’m currently swapping a 383 big block into it. I have the engine all ready and I will be getting the conversion motor mounts this Friday. I’m going with a 727 and a 8 3/4 rear end and I believe I can fit a 10 inch slick on the back without cutting anything up. I still have yet to figure out rear end gears but I’d like to do 1/4 mile drag racing and have it not completely unable to drive down the road. It’s probably going to be a while till it’s up and going because being 17 with a gas guzzling 5.2 magnum doesn’t help my financial situation at all but not having to pay bills kinda helps as well. If anyone that’s done a big block swap would like to give me some tips and help I’m all ears
