67' 318 crank in a 69' 340

I may check around town to see if there is a shop that could weld up this crank . I automatically considered this crank junk because I have always thought that anything cast could not be welded but there may be a process where it could be repaired .
I also wondered with the damage to the crank being so close to the center of the crank if it would be measurable or noticeable when balancing ? The flywheel would add stability and remember this car is just going to be a cruiser .
I'm just thinking out loud . I appreciate everyone's thoughts !! A lot of great ideas and comments here !! Thank you !
Just adding material to stabilize the cut is the idea. The main area of stress is down at the base of the flange where it joins to the crank; the stress decreases the further you go from the center. But if you can find a good low-priced crank like Pishta says, that would be better.
