As far as affordability , you can have the Lightning in the 14's with just a few mods . Why just exhaust issues alone will get you there . The speed density set up is also very "tuneable" and with a tweecer and a chip you can do still more damage to 14's . And it will cost you about the same as what you have in the stock 5.0 in the F-150 . Not only that when it's all said and done it's a Gen 1 Lightning . This is the most superbly engineered truck to hit the market in it's time , and 10 years down the road it's still competitive .
