Since the thrust is up front, cast would likely no longer drive oil pump nor distributor. Seems the twist in the steel would make the bearings tight, and squeel like a pig. But the key would shear before a twist.
Metal has memory. If you bend the crankshaft on your push mower when you hit a big rock you can hit the crankshaft with a big hammer back into place.
Why does it have to shear the cam key? The key is tightened to the gear and cam with a bolt.
Only in Deliverance do you have to squeal like a pig.
Not saying the cam is Twisted just saying there is a possibility.
