86 Black Roller 318, swap/interchange into 72 318

What's wrong with using the 318 crank that is already in the engine? Even if it's cast, How many broken 318 street-cranks have you ever seen? or heard of?
LMAO! That’s a 100% correct statement from the 318 hater.
:poke:

Seriously folks, a 318 crank will work great.
