Hey guys,I’m new to this,and this seems to be the only place I can get answers from. I own a 2003 Mustang with the 3.8 liter. It has 190,000 miles on the car. The car itself does really well besides a rear main seal leak and a couple parts I’ve changed out. It has a ton of value to me being it was my first car and I would love to still keep it in the family. I’m urged to swap the car to a v8,and I know it takes certain things. But can anyone here tell me what I need? How much it’ll cost? I’m a 19 year old with a full time job,and it pays quite well so the money isn’t an issue. I just want a 2v 4.6 in it. Will I need a new K-member? Motor mounts? Etc. HELP
