88 shelbyz 300+ horsepower/trade for 73 an older dart (slant 6 auto preferably)

ok guys,this was going to be my son's first car...i had my fun with it and had planned on passing it on. he's decided he'd rather have an ol dart like dear old dad (i guess). i have a stock parts car,and had planned on putting this back to stock for him...i will include that car also.
in its current form,its a wonderful lil sleeper. mustangs never know what just hit em! im estimating 300+ horsepower,but have never dyno'd it. with all the mods...and the seat of the pants feel its WELL over the 300 mark. you get 3000rpm's in this thing and it literally pulls like a bigblock from there! wife wont even begin to get back in it. scared her much worse than my 340 dart ever did. way too much car for a kid anyway imo. ive let it boost to 25psi a couple times,and the computer/fuel system is good to 29psi. high test gas is a must in this car! too many extras to list!
the parts car is a 87 shelbyz intercooled car also. there is another radiator/intercooler and 5 speed trans in the trunk. the title somehow got screwed up on that car. bad fuel pump kept me from hearing it run- but the previous owner said it ran great.
we're looking for a 73 or older 2 door dart. we'd prefer a slant 6 car. we understand that we'd be talking about a project car,and we're ok with that...but we dont want a total rust bucket.
we're located in 24064 va. and would like to keep our traveling within a couple hundred miles if possible.
we have it listed on craigslist for $2750/trade not including the parts car. i figured probably $3200 for all of it would be fair considering that wouldnt buy the motor in the red car....
interested?
