Re: v8 or v6? Which is a better choice overall?
I just baught a 4.7L, I also have a 3.7L... Depending on what you plan on modding is key. My 3.7L with lift and tires, intake, powerwire, ect gets 12mpg. On my first ride home with my 4.7 I averaged 19mpg. There's also a nice rumble under the hood and shes a bit more torque happy. The 3.7L is a marketing scheme IMO, the 4.7 performs just as well in the MPG area. As my expirence goes.. way better.
