General Slant 6 Input Required

keep in mind that anytime a liquid (gas) evaporates (atomizes), it cools. think swamp cooler. if you don't maintain some heat it becomes harder for the fuel to atomize. even in the desert. notice that I live in Las Vegas, also the desert. by using manifold heat it gives you a more constant manifold temp. to tune to. watch the video posted by slantsixdan in the one thread. in my opinion ANY street driven carbureted car should have manifold heat, it wont really heat the intake charge enough to matter, but it WILL help fuel atomization. you will notice better throttle response, better performance, and increased economy.
