Hello
 

Wanted to introduce myself. My name is John I am retired and I drive a 2003 Ram 1500 Quad cab. Looking for some info on engine updates or swaps. I have a 4.7 in mine now and want to go bigger without a hemi if possible. Also would like street gears instead of tow. I don't tow trailers much so I need a happy medium with a little bit more on the horsepower. Any advice would be appreciated.

Welcome to DF! We have a section just for you. In fact, we even NAMED it after you. :) Nevermind that it was here before you were. :D

Hemi swap is going to be easiest for your truck, there are numerous threads of that nature in the 3rd gen section. Check 'em out.
