I picked up at auction, several 455s, 2 400 g blocks and a ton of other stuff, question I have is 1 of the 400 has a curved oil fill tube,what is the significance of the curve? don't have pics yet,dont even know all I have till I sort it out tuesday

 

1968 has curve fill tube.

 

came from AC car in 1968 only.

 

If you check the VIN derivative stamp on that 400, it will start 38xxxxxxx,

 

ok thank you
