Could be an improperly done brinnel (hardness) test

that is definatly an x file,maybe something was dropped on it or slightly dented the crank and someone did a small drill to smooth it out ? dont think its going to affect a std engine,just for a talking point DJ used to use a tiny drill bit on his forged pistons if they developed a crack so it would not go any further ,just goes to show how much of a budget the team was on in the early days.

I agree it's crazy why . Yes in the early falcons they did . I'm not 100% sure exactly which. Might been pre XP ? Might also been to do with some early 6 cylinders , 144 , 170 etc had a very small bellhousing pattern at the motor side and hence smaller bellhousing. Those I think had the Ford o matic but when they went to the 200 auto went to the BW35 Came across it also when a friend got a U.S Falcon , was a 3 speed manual 6 cylinder. When I built a C4 to go in it with a 302 the tunnel needed work
