I was planning on buying a 5.9l V8 for my 98 Dodge Dakota, but I found on a site that there is a Dodge 318 Engine that is already out of the truck and will fit in my Dakota. I have a v6 mag in my truck right now and I'm looking to beef it up with a v8 so that my truck can get much better sound, power and speed. He is asking $550 for the engine OBO, or I could just get the 5.9 liter for $850. What is better for me to get? Im looking for 1) awsome exhaust sound with a cherry bomb and dual exhaust. 2) Better speed 3) more power. Thanks
