The really big news is... was this crank in a Toronado engine? No. An
H/O engine [as owner said rumor was]? No. This forged steel 455 crank was
right out of a freshly dismantled, numbers-matching.... 1968 455 low compression,
presumably 2-V engine, car possibly equipped with a tow package. This has
been confirmed by another lucky person. Supposedly forged cranks came in
every 455 produced during the first month of production for the 1968 model
400943 crank, numbers barely visible, on the rear weight. Notch in rear
face is a 'rounded-L' shape, longer than say a 425's L, and the corner
is smooth, not a nice right angle. Just like Mondello's tech manual shows,
except he shows a sharp corner there. Forging flash removal left a very
wide "part line" as per usual for a forging. The front throw has AC
stamped in it.

Motor mounts were on the forward pair of holes, and only the rear block
drain holes were drilled, thus negating the theory that it was an H/O motor.
