That question is way too obscure to answer correctly. A simple solution would be to supercharge the current motor, but then you are going to have to worry about the bottom end. You could build the bottom end, stroke it, supercharge or turbocharge (there is lots of room in there) and have PLENTY of power. But remember, you are still in a truck so it is not going to be a sports car, just a truck that is fast in a straight line. DO NOT put big wheels on it unless you upgrade your brakes cause i'd hate to have a truck that is fast in a straight line that CANNOT stop.
