Did a 518 behind a 500''RB.Had to cut off the small block bell and install a bolt on JW bell. Uses the front pump bolt holes.This was in a street car and was fine. Tough like a 727. That was back in 2003.I have kicked around the idea of putting one in my old 1 ton Dodge.

had this 518 in a 73 1 ton car hauler.
swapped the car hauler to CTD 5 speed.

Now the 518 is in a 72 Dart 540
