modern muscle
Realistically you can buy 3 or 4 used 300 HP V6 Camaros, Challengers or Mustangs for the price of one nice 340 Dart or Duster. Arguably the modern vehicle will be faster, safer, more comfortable, handle better and get better mileage...probably 30 mpg or better with air conditioning. But I think the V6's may fall more into the sports car category and you have to spin them to make power. Still, their is no replacing blowing the tires out at will with a small cam 340! If want Modern muscle in a big power V8 you need deeper pockets.
