thanx so much for info folks. new update. motor is original 307 so 85 and back. 2 piece rear main. flex plate came off a mid 70s 350. 307 has very small balancer on it. flex plate has a slug tacked on it and a rectangle weight both on motor side of flex plate. have another flex plate from a 305 it has nothing on it. im assuming first mentioned flexplate will not work but one from 305 will. seems very confusing. lol im trying to find out from previous owner if crank in 307 is original.
