And just like Lazlo said, if you want a 60's or 70's style car (like a gasser...you know, a fad car destined to go the way of the pro-street cars of the '80's...wait that already happened ) it can be done for much cheaper. You'll still spend close to $3K all said and done IMO though. New steering box, power steering, rebuilt steering linkage (that's $1K right there), decent disc brakes and hubs, proper booster, M/C (another $500 at least), control arms with increased caster, shocks, springs, front sway bar (another $750 to $1500, varies greatly)...it adds up fast.
By robbing my stash a little I was able to do all the above for 30-40 cents on the dollar of your cost estimates. For example MID 70 Camaro prop valve free and 72 Monte Carlo rotors free. Just added. 5 degree stock appearing control arms to 55 at $229, why because tubular would look like crap on my car. To me doing more with less is half the fun.
