Do you have all the components on hand (vehicle, drive train, etc.)? What kind of shape are those in?
Are you going for a "factory fresh restoration" or will there be some mods?
Unless you have an original SS car from 1961, you probably have a "replacement" engine in mind from another vehicle. Are you planning on making that look factory correct or something else?
Going with the original interior patterns?
Are you doing the work yourself, or are you hiring it out?
Let us know what your objectives are and your talent level and we can give you some guidance, but you get to make all the decisions (and spend all your money).
Cheers!
