I just have a few questions reguarding my truck. I'm not a hot rodder (although I wouldn't mind). I have a 2002 GMC Sierra and I had to store it at my mom's house to come to japan. She hasn't even started it and let it run for almost 3 years. I was looking into getting a new crate motor and dropping it in my truck but I can't seem to find a fuel injected crate motor online. I guess I just don't know enough about the internet yet to find what I want. If I get a carbureted engine what all kind of work am I looking at? How big of engine would you all recommend? I thought about a 350 but I'm also looking at gas mileage. What will I have to change to make it work? Where in the world do I find a new transmission? I can find used and rebuilt but not new, it would help if I was in the states to be able to ask and drive around to transmission dealers, but I don't have that luxury. Last thing, what brand of computer chip programmers (Hypertech, Superchips, Jet, etc.) are best or most widely recommended? Thank you in advance for your time.

The engine in your truck is based on the LS1 found in corvettes and camaros. It is highly capable, sophisticated, and takes advantage of some serious technology. Swapping to a carb won't get you any kind of decent mileage.

The truck engines were offered in several displacements; 4.8, 5.3, 6.0, all with the same external dimensions and only minor differences between them. You can swap in a 6.0 pretty easily if you don't already have one.

Getting really nice power out of those engines is like a walk in the park.
