The engines are linked together with a large, four row chain coupler, that was special made just for this boat, designed by Bill Clark. The forward most engine has had it's crank snout cut off, and a much larger Chrysler sized snout left-hand threaded and welded onto it, for strength. A stock 327 Chevy crank snout would snap off easily if you linked it to another engine. The special drive piece is double keyed, ( like a blower hub would be ). I even inherited the very blueprints that the coupler was made from! There's two of everything in the set-up, two batteries, two starters, save for the fuel pump...there's only one Hilborn pump and it's on the rear engine, and both sets of injectors have been flowed by Hilborn to operate from one custom pump. Because of there being only one pump, you cannot start each engine by itself, they both operate as one. There are two mag switches, and two starter switches ( starters you throw at the same time). Killing the engines is done like any other injected engine by pulling the single fuel shut-off. The only hassle is squirting ( priming ) all 16 injectors just prior to starting. Both engines run 13 to 1 compression pistons, Engle solid cams, steel rods, small journal Corvette steel cranks held by stock two-bolt mains with "straps". Ignition is Hunt Vertex, Hilborn Injection, heads by Valley Head Service, fuel is 30% nitro/70% methanol. There's 45% in the box and the original Stellings two blade underneath. The rudder was shortened back in '66. Have I gotten too technical?
