Hey Guys, Thanks! for the info.... Upon further inspection after reading the post from MoparJoe...I've checked the the rods, & they're still bolted together on the crankshaft. The cases are split, but the crankshaft, cylinders, pistons, & head are still together in the top half of the cases, & all of these parts look perfect, except the the hole in the top case. My problem has got to be in the transmission, because there is a broken shaft & gear. Also, the hole in the top case is actually at the very back of the engine....If I could locate a good bottom end, I feel pretty confident that my project would only need to be put back together. I'll post pictures soon. Thanks
