ok ive been trying to make the best choice

my dad wants me to get and 1975 nova and fix it up with him but i dont know how much thats really gonna cost me because i can find a nova with a allright body for about 1500-2000 but after that wat is it gonna cost me because im gonna need a 350 small block and a 350turbo trans that can handle it a rear end so how much do u think i would be looking at to fix up a nova........and do u think it would be worth the head ach???????????
