390 vs 408

My opinion for whatever it is worth.Maybe not much to some people.I just sold my '70 Challenger I built a Hughes 390 stroker motor with the Magnum heads and loved it. If you build the 408 you will get a little more power.Depending on what you are driving now you might be perfectly happy with the 390. I had 3.55 gears in mine then when i went on road trip i used hwy gears and with the torque the stroker puts out either will still keep a smile on your face.
