forged or cast torque converter??

i'm sorry the title is a bit off. I didn't mean if the TC is forged or cast, but more along the lines of its application....for a forged or cast crank.

i'm 99.9% sure its an internally balanced unit....for forged crank.....reason is because there are no weights anywhere on this thing. there is also no drain hole....I rotated the motor all the way around and checked....which as another member has pointed out...could mean it is aftermarket.

the car is a 70 swinger...but has the wrong crank....the crank is from a later mopar....serial number for 72 up 340....so its cast. womp womp. it'll work, I just need to make the harmonic balancer and torque converter match.

I just wanted to get everyone to confirm with my thought that it is the wrong torque converter for a cast crank.

flexplate would be a good option, but this will be a good chance to get a better stall on a correct torque converter....and to take the tranny out to stop all the stupid leaks, not that i'm looking forward to that without a lift and in a packed garage. yippee!
