Best advice I can give is there is an azz for every drivers seat. Someone will appreciate the build for what it is and will have to have it no matter what direction you choose. If the paint is decent then go with it. Same for the engine if it is a good 340 or 360 then use it. Hemi swap is not cheap and can nickle and dime you to death. If you build a well put together cool car it will sell.
