The motor was rebuilt as was the distributor. The dist by a guy with 60 yrs experience working on Fords...I have the motor on TDC, when I put the rotor at #1 cylinder and drop it down. I cant get it to go all the way down. I used an oil primer and the pump is working fine. I can see the top of the shaft when looking down the distibuter hole. When It would not go in, I turned the dist. slightly in both directions. no help. I used the oil pump primer to turn the shaft, about 8 times, no help. I even turned the crank by hand and it still won't go in.....Any Ideas?????
