whats going on guys i currently own a 2004 mustang gt with a 4.6l v8 16v with a transmission of 4 speed automatic and i want to swap it for a 5.0l v6 for a bit more mpg. was wondering if i can get the process done for free if i sell my v8 and purchase a v6. im a teenage and would not trust myself to make the swap so will i get enough money from the v8 to buy and pay a shop to install a v6 for me?
