Thanks - on the 5.7, I love it. Absolutely no issues. Good power and torque - just have to watch the throttle a little to keep the axle's in one piece. The Chevy's backed by a NV4500 tranny. Nice crawl ratio and only runs at a tick over 2.2k rpm's at 70mph. Kinda the best of both worlds. All that said, I'm always thinking of a diesel.....guess the grass is always greener on the other side!
