[Three Peaks]

Do whatever you have to do to find that piece. Same thing happened to a friend of mine about 30 years ago. Dropped a 1/4" nut that held his air cleaner on down his manifold and didn't find it. We figured it fell somewhere on the frame where it couldn't be seen. Destroyed the 340 HiPo engine in his 70 Cuda the next day. The damage was amazing- broken pushrods, piston skirts knocked off, metal in all the bearings, bent valves, damaged piston domes, etc.....
