To get a better powerplant in my truck. I have helped in a few ls swaps( in a gm of course). I will probably build more power down the road, but I need to get the basics under my belt. I have a buddy that is installing a 5.7 in his son's challenger project, he is using the mopar performance harness and computer for simplicity. I think that there may be better options out there.

Is a pre eagle 5.7 worth buying?
