fs.87 mustang

ive heard this thing run, sounds mean and ran like a raped ape, has a tuning issue probably something simple, heres some more info, new distributer, fuel filter, tires in back are bald but i gave him like 6 meaty tires for it im sure hed throw in, some of the bodywork isnt totally perfect(sand scratches) but its a solid car and with a lil tlc would be a sweet summer ride
