 We'll be using Golden Eagle to do the sleeve work on our block with ductile iron sleeves that will be strutted; the strutted nature of these sleeves is very critical. As opposed to an open deck, it's about as close to a closed deck as you can get without any heating challenges. If you look about a quarter-inch down from the deck surface, you'll see these pillars that help stabilize the sleeves. At high rpm, you don't want your sleeves to move around, which can cause leakage between the head and gasket. A strutted sleeve will not only stabilize but it will keep the compression within the cylinder walls, in the engine where it belongs. A closed deck will just give you heating problems that are unnecessary. We'll have a 90mm bore, which is about as big as I would go on a NA street/strip application and will un-shroud the valves and help flow better to the combustion chamber. Pistons will be from Arias with ceramic barrier top and friction-reducing, molybased coating on the piston skirt. The ceramic coating on the piston dome helps to keep the heat inside the cylinder where it belongs, so that when the explosion occurs from combustion, you don't lose that heat to the surroundings. Engines are nothing but chemical-to-heat-to-mechanical energy converters. You want to create a chemical reaction that can produce heat, which can then be harnessed, and if kept in intact, you will be allowing it to do mechanical work to the piston itself, which then transfers to the crankshaft, which means you've done your job. Allowing heat to escape from the combustion chamber during those events hurts power.</p>
