Currently have a Cuda with a '69 Hemi and a 727. I am going to be pulling the Hemi out and dropping in a '77ish cast crank 440.
The question I have is in regards to reusing the torque converter and flexplate.
I am thinking that I need to get a B&M flexplate in order to use the existing converter.
If I need the B&M, which one do I need since they list multiple big block plates?
