When it comes to V8 motor swaps, everyone wants to talk about things like horsepower, torque, what it sounds like or what it looks like under the hood. But the one thing that nobody really wants to talk about, is heat. With big power comes high temps under the hood and it's a real problem and one that can be difficult to keep in check. Fortunately, Motech has done a great job of addressing the cooling needs of Moby's brand new 6.2L Gen-V LT engine and I would have to say, they've even gotten it to run measurably cooler than the LS we had before. In fact, for the better part of a week now, Cindy and I have been pushing Moby hard, bombing him across the desert and taking on the rocks and so far, he's been able to keep both his coolant and transmission temps, well under control. However, we knew there was still one test that we needed to do. One that we've always found to be a challenge, for any engine and that's to make a long, slow and windy climb up a desert mountain and in the kind of triple degree heat that you can almost always find out in the Nevada desert. In this short video, you'll get to see the results of this test.
