Help needed for my project car

I'm currently trying to build my 66 Cuda and being a guy who loves cars who threw himself into a project not knowing much I need help. I've got my 383 almost done being built and now I need help with just about everything else. My dad's been outta the car building game for yrs and never really built the cuda he had. So any help or tips would be great. Oh and my engine has been built for performance so I'll need to figure what I need to make it work. Thx for any help in advance
