Bingo. That and the tuning put into it makes a difference. I was very impressed with what could be done with that Terminator X setup. The wiring was simple, fired up and drove the first time, made multiple big power pulls on the dyno with no signs of issues at all.
Turned up and on a safe tune it will be 1,000 wheel no problem.
So, your setup with a 4.8 and halfway decent parts will be perfect for what you want to do. LS swaps are done because they work, are reliable, make good power, and aren't expensive.
