Going from a 5.7 to a 5.3 just seems like sacrilege. Go big or go home. Already sourced a few 6.0s on craigslist. Time to start being a prostitute to pay for it!
 
yea but a 5.3 has like 50 more hp or more depending on what year. and get 5-8mpg better than the 5.7.

cubic inches arent everything. modern technology can make smally motors much more powerfull and efficent.

This. Don't over look a 5.3. They are usually cheaper as everyone wants a 6.0.
