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?

two. one in a absolute beat to death, ragged out work truck that was probably run low on oil more times than i've gotten laid. the other in some johnny hot **** motor that had a crank turned .050 with some ungodly amount of compression, stall and gears.

to clarify, and absolve myself, i was not the owner, care taker or behind the wheel at the time of these events.
